New in Mono for Windows 6.6.0.157 Preview (Nov 26, 2019)
- Runtime:
- Improved reliability of the Mono Crash Reporter:
- When Mono crashes it tries to dump a stack trace and other useful info to give developers a way to look into the issue. The crash reporter is now more reliable in certain edge cases.
- WebAssembly:
- We continue to work on making our WebAssembly support better. Various sets of issues have been resolved in this release and general performance and feature work is happening as well.
- Community improvements for AIX/PASE and Haiku:
- The ports for these systems received a bunch of improvements from community contributor Calvin Buckley (@NattyNarwhal).
- Class Libraries:
- CoreFX integration:
- We continued to replace some of our classes with the implementation from CoreFX to improve performance and compatibility with .NET.
- Tools:
- .NET 4.8 reference assemblies:

New in Mono for Windows 5.10.0.140 (Mar 2, 2018)
- IN DEPTH:
- Runtime:
- Interpreter:
- The interpreter is now compiled in by default into Mono, and you can use it by running mono --interpreter. Check out the recent interpreter blog post for more details about this work.
- We are getting closer to get the interpreter working with JIT/AOT and on mobile:
- exception handling and debugger support has been unified with JIT/AOT
- we support more AppDomain and Remoting cases
- It is not yet as feature complete as the JIT, so there will be some behavior differences or breakages; we are currently working on making our complete test suite pass.
- Default Interface Methods:
- The runtime now supports Default Interface Methods, we now only miss the C# compiler support.
- Mono SDKs:
- This is a new way of building Mono for some of the platforms that we support: Android, iOS and WebAssembly. The goal is to move most of the build logic into Mono so that we can more easily make changes and test those platforms as part of CI.
- You can find some documentation at the README and Makefile build targets.
- This is still a work-in-progress, we’ll make it easier to use with upcoming releases, and more documentation will also be added.
- WebAssembly port:
- This is the first release where the interpreter can reliably run most of the class libraries test suite. Multiple bugs affecting the Basic Class Libraries were fixed. The WebAssembly port is leveraging the work done around Mono SDKs to provide an improved developer experience to those working on mono. While there will be no official release at this point, the adventurous ones can try our code drops directly from CI.
- Dedicated Coverage profiler:
- The coverage profiler has been extracted from the log profiler, making it much more lightweight. It also removes the dependency on mprof-report to generate the XML report, and instead generates the report directly. You can find more documentation by looking at the COVERAGE PROFILER section of the mono-profilers man page.
- Support for Android Unified Headers:
- Android NDK unified headers required changes to the way Mono detects real-time signal definitions (SIGRTMIN/SIGRTMAX), as well as a number of workarounds for 64-bit API declarations on target platforms (< API 24) which do not have the correct declarations. A number of compatibility tweaks was also done to declarations of fgetpos, fsetpos, mmap, sendfile and statvfs calls. Mono builds targeting Android require that the __ANDROID_API__ macro is set to the target platform level (e.g. 21, 24 or O)
- ARM Memory Barriers:
- Explicitly encode memory barrier type on ARM64, instead of relying on undefined behaviour according to the ARMv8 ABI. This is to respect the ARM specification closer, reducing the risk of hardware-specific bugs.
- AOT Size Reduction via Code Deduplication:
- We now support deduplicating generics code across assemblies. For example, code for List<int> is now deduplicated for usage in the user code and System.dll.
- CLASS LIBRARIES:
- The recently announced .NET 4.7.1 is now supported and available as a specific target via MSBuild configuration.
- The System.Data assembly was fully replaced with CoreFX implementation resolving many limitations and corner cases issue we had as well as implementing missing features and APIs.
- Significant parts of System.Security assembly implementation were replaced with CoreFX implementation.
- TOOLS:
- C# compiler:
- The Roslyn compiler (csc) has been updated to version 2.6.0 which includes all C# 7.2 features.
- The Mono C# compiler (mcs) gained support for the following C# 7.x features:
- default literal
- non-trailing named arguments
- discards
- tuples implicit deconstruction
- generalized async return types
- stackalloc to Span assignment conversion
- ref struct
- readonly structs
- F# compiler:
- The F# compiler was updated to the latest 4.1 version.
- The FSharp.Core.dll assembly is no longer installed into the GAC, solving many problems users faced when using NuGets.
- MSBuild:
- MSBuild was updated to the latest version available.
- Mono’s list of incompatible NuGet assemblies was extended and updated which should help with NuGets which bundle the same assemblies as installed by Mono as those are now skipped.

New in Mono for Windows 5.4.0.201 (Oct 17, 2017)
- HIGHLIGHTS:
- NuGet updated to 4.3.0
- IN DEPTH:
- Runtime:
- JIT Job Control:
- The Runtime now controls concurrent method compilation. It avoid multiple threads compiling the same method at the same time and limits the number of threads simultaneously compiling.
- This shows up as performance issue with applications such as Roslyn that very quickly ramp up a lot of threads.
- Array element store optimization:
- Optimize array stores of non-final ref types.
- Load scalability improvements:
- Move a few hot data structures in the type loader to use lock free reads. This shown up a scalability botheneck with Roslyn and Visual Studio for Mac first project load.
- ValueType write barrier optimization:
- Optimize GC write barriers when value types are involved. This shown up as a performance issue with Roslyn.
- Make jit method table resizing more scalable
- The original table resizing code would count the size of the table on resize, this works fine for small programs but proved to be a problem with Visual Studio for Mac.
- Reflection queries scalability improvements:
- Reflection queries must be cached by the runtime as two identical queries must return the same objects. It now use a lock free data structure for reads. This shown up as a performance issue during Visual Studio for Mac first project load.
- Intrisificy Marshal.PtrToStruct for blitable types
- This avoid boxing and unboxing an intermediary object. This results in a 30x speedup on a microbenchmark.
- Revamped unaligned memory access support:
- As part of our work to support dotnet platform advances, proper unaligned access was missing from the mono runtime. This feature is used by the new Span type and now it works with ARM cpus.
- Interpreter works in JIT restricted environments:
- There are a few things in the interpreter that still require machine specific trampolines that are written in assembly or managed code. We used the JIT infrastructure so far for that, but now we added plumbing to the AOT compiler so they can be pre-generated, and thus the interpreter is usable on platforms where code generation is not allowed during execution. See the interp option in the man page.
- Interpreter supports ARM and ARM64
- We added support for those architectures and also test them on CI.
- Class Libraries:
- Integrated AppContextSwitch code from reference sources which allows all of its compat switches to be used.
- Added reference assemblies for .NET Framework 4.7. This allows you to build libraries targetting .NET 4.7 using Mono’s msbuild.
- Tools
- We updated the NuGet command line tool (nuget) which is bundled with Mono to version 4.3.0.
- We updated MSBuild to the latest 15.4 release.
New in Mono for Windows 5.2.0.224 Service Release 4 (Sep 21, 2017)
- Highlights:
- mono command defaults to 64bit
- Experimental Default Interface Methods Support
- Strong assembly names:
- Mono will now optionally respect public keys and version numbers when loading strongly signed assemblies. If Mono is invoked with the --assembly-loader=strict option, then requests (whether via a static assembly reference, or using an assembly name using the reflection API) that include a public key token and version number will only load strong named assemblies with a matching token and name (respecting any bindings in relevant app config files).
- To debug the assembly loading process, set the logging environment variables to trace level “info” or lower and trace filter to include “asm”. (See Logging runtime events.)
- The current default behavior is the same as in previous Mono versions. It is explicitly available with the --assembly-loader=legacy option.
- Experimental Default Interface Methods Support
- We added experimental support for the current prototype. Check the C# specs
- Class Libraries
- System.Numerics.Vectors
- Multiple fixes and new intrinsics added. The library is now considered ready for general usage.
- .NET Standard 2.0 groundwork
- We’ve done all the groundwork to support libraries that conform to .NET Standard 2.0. Loading and running a library compiled against the 2.0 standard should work fine, tooling support (i.e. creating a .NET Standard 2.0 library) is still in preview though.
- You’ll need to install the .NET Core 2.0 SDK for tooling support as we use the MSBuild tasks which are installed as part of the .NET Core 2.0 SDK, similar to how Visual Studio/MSBuild on Windows does it.
- Reference assemblies
- The reference assemblies were updated to provide the .NET 4.7 API set.
- Runtime
- mono command defaults to 64bit
- The mono command now runs as a 64bit application by default. You can use the --arch=32 option to run Mono as 32bit again.
- Optimized Array Stores
- Added a fast path for storing on array of reference values when the stored value is of the same type of the array element type.
- Class Initialization Improvements
- Do hold any runtime locks while running the class initializer. This improves startup scalability.
- Reduced minor collection pause times
- Made the runtime tables used to store reflection information generational, so the GC can avoid scanning them during minor collections. Those tables can become significantly large on workloads like Visual Studio for Mac.
- Interpreter passes the majority of the JIT test suite
- Major progress was made on the interpreter front. It can now run non-trivial programs.
- Misc
- Internal Documentation
- We continue to publish internal docs for mono, making it more convenient to browse and search the Mono runtime internals and associated documentation.
- Static Analysis
- In order to holistically improve the correctness and stability of Mono, we have been investing effort in custom static analysis tooling, which will be deployed as part of our continuous build to rule out certain classes of bugs. Recently we have made progress on minimizing the amount of manual annotation work required to add new analyses, making it easier for us to verify more properties of our code.
- Mangler V1
- Managed methods can include a dizzying array of attributes beyond the actual method code. The mangler encodes the attributes which are necessary to create a unique name for each method. If two methods mangle to the same string, they are the same method. This can be thought of as a primary key for each method, and extends to methods which are mono wrappers. Internally, mono is using it to build a deduplicating pass to remove binary bloat associated with generics.
- Safer Getenv
- The functions g_getenv and g_setenv are neither threadsafe nor reentrant. Subsequent calls to g_getenv can cause previous strings returned from it to point to garbage memory. This was leading to issues with System.Configuration that could be seen with HttpClient. Now we lock around these calls and return duplicated memory. This is a serious API change to g_getenv. The string returned must now always be freed. We don’t expect many embedders to be using the version of eglib that is linked into mono for other functions. Those who do might want to check that this change does not introduce memory leaks.

New in Mono for Windows 5.0.0.100 (May 12, 2017)
- Highlights:
- Shipping Roslyn C# compiler to enable C#7 support
- Shipping msbuild and deprecating xbuild for better compatibility
- Enabling concurrent SGen garbage collector to reduce time spent in GC
- Introducing the AppleTLS stack on macOS for HTTPS connections
- Continued Progress on .NET Class Library convergence
- Updated libjpeg in macOS package
- IN DEPTH:
- C# COMPILER:
- The Roslyn C# compiler is now available on Mono and it’s called csc. It’s the same compiler available on Windows / Visual Studio with full support for C# 7. Both msbuild and xbuild have been updated to call the csc compiler under the hood instead of mcs.
- Replacing mcs with csc in user scripts should be straightforward but small issues can arise as command line arguments accepted by csc and features are not identical to mcs. For example, csc generates Portable PDB (.pdb) debug files instead of Mono’s MDB (.mdb) format. It also can’t do full signing on non-Windows platforms, use the /publicsign switch instead or use delay signing and sign the assembly with the sn tool after the build.
- C# 7 adds a number of new features to the C# language:
- out variables: ◦You can declare out values inline as arguments to the method where they are used.
- Tuples ◦You can create lightweight, unnamed types that contain multiple public fields. Compilers and IDE tools understand the semantics of these types.
- Pattern Matching ◦You can create branching logic based on arbitrary types and values of the members of those types.
- ref locals and returns ◦Method arguments and local variables can be references to other storage.
- Local Functions ◦You can nest functions inside other functions to limit their scope and visibility.
- More expression-bodied members ◦The list of members that can be authored using expressions has grown.
- throw Expressions ◦You can throw exceptions in code constructs that previously were not allowed because throw was a statement.
- Generalized async return types ◦Methods declared with the async modifier can return other types in addition to Task and Task<T>.
- Numeric literal syntax improvements ◦New tokens improve readability for numeric constants.
- The new features in C# 7 can also be explored interactively as a Xamarin Workbook.
- The Mono C# compiler is still available but it has not been updated to include C#7 features. The compiler is still maintained and all reported bugs have been fixed.
- MSBUILD:
- Over the past year we have been working to integrate the open-sourced msbuild build tool into Mono. It is now available as part of your Mono installation, and it is the same MSBuild that is used on .NET on Windows.
- This resolves numerous incompatibilities we had in our previous xbuild implementation.
- XBUILD:
- Mono’s historical implementation of MSBuild called xbuild is now deprecated. We encourage everyone to switch to the msbuild command which is now available on Mono as well.
- REFERENCE ASSEMBLIES:
- The reference assemblies were updated to fully match the .NET 4.6.2 API set. This means that you no longer get compilation errors about missing classes/methods when building against one of the .NET profiles via msbuild/xbuild.
- Note that at runtime certain APIs that Mono doesn’t (yet) implement will still throw an exception.
- TOOLS:
- The pdb2mdb tool was updated so it no longer crashes when run against an assembly that has a Portable PDB debug symbols available.
- CSSHART:
- The csharp REPL and scripting tool, which is based on the mcs compiler, now supports script-and-REPL-specific command line arguments, which are delimited by either the -s or -- arguments. These arguments are further made available in the Args global for easy processing in scripts.
- It is now possible to write self-executing scripts with simple and unambiguous access to command line arguments:
- #!/usr/bin/env csharp -s
- Deprecation of Mono-bundled version of NUnit:
- Mono used to ship with a forked copy of NUnit 2.4 that we used for testing Mono itself. For historical reasons it was never updated and is ancient at this point (it was released nearly 10 years ago!).
- We moved to NUnitLite for testing Mono so we decided to deprecate the version we ship.
- The nunit-console command will print a warning now. Compiling new projects against the NUnit DLLs from GAC will fail with an error message (existing test assemblies continue to work).
- We recommend that you use a recent version of NUnit from NuGet or the project’s website instead.
- CoreFX + Reference Source Adoption:
- As we announced we are adopting a new strategy to share code with .NET. With this release we started this effort where the code is shared between .NET Core and Mono and not just the Reference Source release.
- Windows:
- The build system was fixed so it works without setting the git config --global core.autocrlf input setting which makes building Mono on Windows easier.
- RUNTIME:
- SIMD Acceleration support:
- Generating SIMD accelerated native code for the classes in the Mono.Simd assembly is deprecated in this release, and it will be removed in +2 releases. Users should transition to using the Vector classes, which are part of the official .NET class libraries.
- Environment Memory Management And System.Configuration:
- As per the Unix specification, getenv may return a pointer into static memory. Future calls to getenv can overwrite the memory returned from previous calls to getenv. Mono kept many pointers into this memory while concurrently calling getenv on multiple threads. We now lock around the environment-changing functions and to duplicate all returned strings.
- Unfortunately, Mono will use the environment to find which configuration file to read for System.Configuration. Configurations that were set might not have been used, as managed code was seeing nulls. This is how the bug surfaced, it is not hypothetical. Users who set a custom configuration file (via MONO_CFG_DIR) are encouraged to check that using previously-ignored configuration files does not lead to unexpected breakage.
- Match semantics of rethrow instruction with .NET runtime:
- Mono used to cut off the stack trace at the point where an exception is re-thrown, however, it should retain the stack trace if rethrow is used.
- Experimental runtime interpreter:
- We revived the interpreter back from the old days (aka. mint). It now supports generics, and was updated to match internal API changes. It is disabled by default and shouldn’t be used in production yet.
- The interpreter will be an execution option to the current runtime.
- Clean-ups around native crashes:
- Native crashes now end up a single handler mono_handle_native_crash, that tries to provide as much information as possible. Also, SIGILL won’t get wrapped into a managed exception anymore but results into a native crash.
- Internal Documentation:
- We have enabled Doxygen for documentation of runtime internals. Going forward, this should help us onboard new contributors and make the codebase easier to navigate and understand.
- Lazy array interfaces:
- One curious aspect of C# is that arrays implement invariant interfaces as if they were covariant. This happens for IList<T>, ICollection<T> and IEnumerable<T> which means, for example, that string[] implements both IList<string> and IList<object>.
- Mono traditionally implemented this by creating the runtime-side metadata for all of those interfaces and that came with an extraordinary memory cost of creating a lot of interfaces that never ended up being referenced by C# code.
- With Mono 5.0 we now treat those interfaces as magic/special and use a different casting code-path. This allows them to be lazily implemented in arrays, which can save a lot of memory in LINQ-heavy workloads. As part of this work we refactored the casting code in the JIT to be simpler and more maintainable.
- Memory usage:
- Improvements in the runtime representation of the type system should yield a 5% memory saving in most workloads. It was achieved by using a more efficient representation for arrays and generic instances.
- A linearizable property bag was added to replace the current mechanism of rare fields in runtime metadata. More rarely used fields were moved to use it as they now use significantly less memory when used.
- SGen Improvements:
- As of this release we are enabling concurrent SGen as the default mode on desktop platforms. This mode significantly reduces the time spent in major collections, by doing most of the work concurrently with the application. In order to use the old serial collector you can pass to the environment MONO_GC_PARAMS=major=marksweep.
- A new parallel SGen mode has been added for majors. This mode uses multiple workers in order to finish a concurrent collection and it is currently experimental. If you are still experiencing large pauses with the concurrent collector, you can try out the parallel mode by passing MONO_GC_PARAMS=major=marksweep-conc-par.
- SGen uses an optimized custom implementation of quicksort to improve the performance of some GC operations. Previously, it selected a poor choice of pivot, which could lead to worst-case time complexity in some circumstances. It has been rewritten with an improved pivot strategy.
- This release includes some performance improvements in ephemeron processing, which also translate to shorter collections. Ephemerons are an internal structure used by the SGen to implement the semantics of ConditionalWeakTable. This also includes a fix for a long-standing leak when using and disposing of a lot of these structures.
- Major block allocation and freeing was tweaked in order to reduce fragmentation of the virtual memory space.
- SIMD Register Scanning:
- Certain compiler optimizations can lead to object references being stored in SIMD registers, for example, during an optimized copy of an array of references. Previously, the runtime did not scan these registers, which could cause objects to be prematurely freed if the garbage collector happened to run while the only reference to an object resided in such a register. The runtime now correctly scans these registers for object references during garbage collection.
- Static Analysis:
- We are investing in static analysis of the runtime to verify our use of locks, signals, and global state. This should help reduce concurrency errors, improving correctness and stability. As a first step, we have already caught some locking errors in the garbage collector.
- Symbolification:
- The runtime crash stack traces now include information on managed stack traces to allow them to be symbolificated. Tooling was adjusted to handle the slightly different format.
- Thread.Abort hardening:
- The runtime was hardened to further its resilience in face of thread aborts. It now won’t abort in-flight class constructors. Thread abort is important for application using multiple AppDomains.
- ThreadAbortException:
- ThreadAbortException remains set during stack unwinding unless manually unset. While inside of a function call inside of a catch block for the exception, it was possible for us to see the set ThreadAbortException and behave as if the call inside of the catch block threw it. This has been fixed.
- Unwinding on Android:
- On a native crash on Android, the Mono runtime tried to dlopen libcorkscrew or libunwind (depending on what is available) in order to obtain a native stack trace. However, this approach was unreliable, as some devices don’t even ship said libraries. Furthermore, Android will restrict the dlopen syscall in an unfavorable way for this approach in a future version.
- We changed our approach by trying to do less work: We now rely on a system process by Android aka. debuggerd to provide us a native stack trace. On some Android versions this requires us to set DUMPABLE.
- Workaround for .NET Standard NuGets on desktop:
- Some .NET Standard NuGets like System.IO.Compression resolve to assemblies that won’t work with Mono on Desktop. To handle this we implemented a series of workarounds:
- Deny loading problematic assemblies. They will be handled as if they did not exist
- Deny remapping to problematic assembly versions. The system version will be used instead.
- Windows Support:
- Mono can now run on Win64.
- Bring PowerPC back to life
- Mono can bootstrap on ppc64le.

New in Mono for Windows 4.8.0.495 (Feb 24, 2017)
- HIGHLIGHTS:
- API Additions for .NET Standard 2.0
- Cross-compilation with MKBundle
- TLS 1.2 support
- IN DEPTH:
- API additions for .NET Standard 2.0:
- We added APIs to comply with .NET Standard 2.0, which is still a work in progress at the time of this writing. Note that in some cases an implementation is still missing and will throw at runtime.
- Please check the .NET Standard repository on GitHub for more details about .NET Standard.
- TLS 1.2 Support:
- Mono now ships with TLS 1.2, powered by Google’s BoringSSL project.
- To use it, you must set the environment variable MONO_TLS_PROVIDER to the value “btls”
- This affects Mono when it is built from source code and is also the stack used on Xamarin.Android.
- Xamarin.iOS, Xamarin.Mac and the Mono installed by the official Mac MDK installer use Apple’s TLS stack instead which uses Apple’s system certificate store to resolve the root certificates, so everything works out of the box.
- On BoringSSL systems like Linux, you can populate the Mono certificate store from the system certificate store using the cert-sync tool. After that, run the btls-cert-sync tool to convert from the old Mono certificate store into the new one.
- On Mac if you compiled and installed Mono from source (i.e. you don’t have access to the Apple TLS implementation), you can use mozroots to populate the Mono certificate stores with Mozilla’s certificates
- Cross-compilation with MKBundle:
- The MKBundle tool has been updated to easily support cross-compilation, instead of using a native compiler to compile a bundled executable, Mono has been altered to support payloads embedded in the executable.
- To do this, use the new --simple command line option.
- You can configure the resulting bundle with some command line options that you wish to pass to the runtime, for example, the following would disable inlining
- The cross-compilation feature requires the Mono team to update the packages on the server and might not be working during the alpha period, but will be available at ship time.
- We have also extended the tool to allow you to configure the environment variables that you wish your bundled executable uses at runtime (for example to set some Mono internal configuration options with --env), distribute native libraries with --library, specify additional character encodings with --i18n and specify a machine.config file with --config.
- For an overview of all the new features, check the mkbundle(1) manual page.
- Runtime Logging:
- The new MONO_LOG_DEST environment variable can set to instruct the runtime where to write the tracing messages to. If this variable is not set, the default continues to be stdout, if the value is set to the special syslog value, the tracing will be sent to the syslog, on Windows it will be sent to the mono.log file.
- The MONO_LOG_HEADER environment variable, if set, will include the id, timestampe and process id on the trace logs.
- Concurrent SGen:
- We now support a concurrent mode for the major collector. As opposed to the serial major collector, which suspends the world, does all the work and resumes it, the concurrent major uses two, significantly smaller pauses. These are the starting pause, which initialises the root set for a worker that runs concurrently with your application, followed by a finishing pause, once the concurrent worker is done, that ends the major collection. In order to use it you need to pass MONO_GC_PARAMS=major=marksweep-conc to the environment of the mono runtime.
- This mode has been present for a few years now, but only over the recent releases (4.4 and 4.6) has it seen significant improvements. These improvements consist in improved memory usage with it, further reduction of the finishing pause and stability improvements. As of this release, this mode has been strongly tested on desktop platforms and we encourage its use there. Over the next releases we plan to adopt it as the default SGen mode.
- WINDOWS:
- Mono on Windows has vastly improved in this release as we make it a first class supported platform in Mono. We placed a significant amount of work on making Mono on Windows pass our test suites and add many new capabilities, like full static compilation (full AOT).
- Mono’s port to Windows now includes the beginning of full static compilation, which will make it suitable to be embedded in UWP apps and is the foundation for more console support.

- Bug Fixes:
- Array doesn’t implement non-generic IEnumerable
New in Mono for Windows 4.6.0.245 (Sep 17, 2016)
- IN DEPTH:
- POTENTIALLY - TLS:
- We have added a new implementation of TLS that supports TLS up to version 1.2 (the old version only supported up to 1.0). This is a completely new implementation, and given that it is new, we do not currently default to it, but we hope to switch to it in the future.
- We have an implementation switcher on both the SslStream and HttpListener classes. The default implementation of SslStream for now continues to be the old Mono TLS implementation, the one that supports SSL and up to TLS 1.0. But it is now possible to switch the implementation to either our new managed implementation or any implementation built on top of something else.
- You can control this with the MONO_TLS_PROVIDER environment variable. The possible settings are as follows:
- default - let Mono choose the best implementation available for the platform, currently this is hardcoded to the old implementation, but we will change this once we complete the audit of our TLS stack, and we might change this on a per-platform basis to use SslStream implementations that use some native library.
- oldtls - Mono’s historical implementation, it only goes up to TLS 1.0.
- newtls - Mono’s new managed implementation, it supports TLS 1.0 up to 1.2
- Any full typename - You can specify a fully qualified .NET Type, this can be used to test alternative implementations without changing Mono’s runtime: MONO_TLS_PROVIDER="Mono.Security.Providers.NewTls.NewTlsProvider, Mono.Security.Providers.NewTls, Version=4.0.0.0, Culture=neutral, PublicKeyToken=84e3aee7225169c2
- For custom implementations, the type should subclass the Mono.Security.Interface.MonoTlsProvider interface from the Mono.Security assembly and have a public parameterless constructor.
- Mono symbolicate:
- mono-symbolicate requires symbols to convert native and IL offsets into file names and line numbers. mono-symbolicate original version required its caller to provide a stack trace along with the symbols to be used. The task of mapping a stack trace to the correct symbols was delegated to the caller. Doing such mapping revealed to be a big usability problem as it was necessary to track the stack trace’s assemblies versions externally.
- Stack trace format changes were introduced to let mono-symbolicate know the symbols of stack traces with: - IL offsets, as there was no way of knowing to which version of the managed assembly the IL refers to. - Native offsets, as multiple .msym are generated and it was not possible to directly link the stack trace to those symbols.
- The problem of mapping a stack trace IL offsets to the correct managed assembly version was fixed by changing a stack frame such as: at StackTraceDumper.Main () [0x00000] in :0 into one as: at StackTraceDumper.Main () [0x00000] in :0 Where the hash looking part in between is the module version ID (MVID) of the assembly module the method belongs to.
- The problem of mapping native offsets to the correct .msym version was done by replacing a stack frame such as: at StackTraceDumper.m__0 () in :0 by one as: at StackTraceDumper.m__0 () in :0 The new stack frame also displays the MVID but after the # it also displays what we named as AOTID, a unique identifier embedded into the AOT compiled assembly.
- With the changes above it is possible to know from the stack frames only which symbols versions are to be used in order to symbolicate it.
- A symbol directory was also introduced, its purpose is to store managed assemblies into subfolders MVID named and native assemblies into subfolders AOTID named.
- mono-symbolicate is now able to retrieve the correct symbols versions from the stack trace, and to symbolicate using the symbols in the symbol directory.
- The changes greatly improved mono-symbolicate usability and eliminated the versioning issues it had before.
- For mono-symbolicate to work it requires a data structure called compact sequence point to be created and stored while compiling IL to native code. The purpose of compact sequence points is to map native offsets into IL offset so the runtime can display IL offsets instead of native ones.
- The memory overhead of using compact sequence points is about 10% of the compiled native code size. The time spent compiling increased by 4%, this is usually not an issue, 2ms for whole mscorlib. With AOT compiled assemblies there is the option of storing compact sequence points externally into .msym files, with no overheads at runtime. Overall the overheads were considered a small price to pay for the huge benefit of being able to symbolicate any future stack trace as long as the symbols are properly stored.
- Mono can still be ran without compact sequence points by doing: MONO_DEBUG=no-compact-seq-points mono Program.exe By doing so Mono runtime will not be able to output IL offsets instead of native ones in the stack traces and mono-symbolicate will not work.

- This Mono release will feature version 1.0 of the log profiler. This is the most stable version of the profiler to date. While there are a few new features, the focus has been on hardening the profiler to run on all sorts of platforms (including Linux, OS X, Android, and iOS) without crashing or otherwise destabilizing the program being profiled.
- New Features & Changes:
- The profiler now has support for gathering coverage data. This data can be processed into XML by mprof-report.
- The profiler will now provide a stack trace with GC handle creation/deletion events when possible, making it easier to track down where a GC handle came from.
- The profiler now uses a real-time signal to do sampling when supported by the operating system. This leads to significantly better signal delivery rates (usually 99-100%).
- The profiler now sets SA_RESTART for its profiling signal to work around buggy code in the wild that assumes that a system call can’t be interrupted by arbitrary signals.
- The profiler now uses a separate thread for sample hit processing, thus ensuring that it will not interfere with performance counter sampling.
- The profiler will now attempt to switch the internal sampling thread to real-time priority scheduling for more consistent sample signal delivery. This usually only works for root.
- The profiler now uses a separate thread for flushing buffers to the output file, allowing it to flush buffers in more places.
- The profiler now flushes all thread-local buffers periodically and during certain global GC events in the program. Therefore, all code in the profiler that manually flushed buffers unconditionally has been removed.
- The command line argument for sampling frequency is now correctly interpreted s the frequency in Hz, rather than the interval between samples.
- The default sampling frequency is now 100 Hz (down from 1 kHz).
- perf support for Linux now works on ARM64.
- perf support for Linux is now disabled by default as it was too unstable on older kernels. It can still be enabled by passing --enable-perf-events to configure if you know your kernel has working support.
- Introduced synchronization point events in the format which can be seen as a sort of ‘memory barrier’. A reader can know with certainty that the profiling session will be in a consistent state at every synchronization point.
- The profiler now emits events for object finalization.
- The profiler now emits more metadata load/unload and name change events.
- Cleaned up the log format to not use LEB128 for data types that don’t need it, and to not emit pointless data that was never used.
- All events in the log format now carry a timestamp.
- Stability Fixes:
- Fixed on-demand heapshots often resulting in crashes due to being processed on the profiler’s helper thread.
- Fixed a GC crash that could occur when sampling and a thread was stopped in the middle of a managed allocator.
- Fixed a stack corruption that could occur in the old sample hit processing code. This code has been rewritten entirely.
- Fixed a crash when sampling that was caused by incorrect snapshot iteration logic in Mono’s linked list set code.
- Fixed a TLS crash that could occur on OS X and iOS when sampling, because sampling signals were being sent to threads before they had finished basic initialization in libc.
- Fixed crashes on Linux when sampling caused by the ELF header traversal code. This code has been disabled as it didn’t provide information that was particularly useful for programmers writing managed code.
- Fixed crashes on OS X when sampling caused by invoking the dynamic linker in the sampling callback (async-signal context).
- Fixed the profiler’s helper thread to reject on-demand heapshot requests when the profiler is not in on-demand mode.
- Fixed a crash that could happen on startup because Mono’s threading subsystem wasn’t initialized yet.
- Fixed the internal profiler threads not detaching from the runtime on shutdown.
- Fixed a number of potential buffer overflows when writing events.
- Fixed a potential hazardous free crash when shutting down the profiler.
- Fixed potential race conditions when doing the final sample dump on shutdown.
- Bug Fixes:
- Fixed many cases where events would be emitted in an incorrect order. This mainly affected sample hit and method JIT events, as well as GC allocation and move events.
- Fixed some class load events that could be lost in the profiler’s writer thread.
- Fixed the profiler missing a lot of metadata unload events because it was shut down too early.
- Fixed internal profiler threads sometimes showing up in thread start/stop events.
- Fixed heapshots and coverage recording incorrectly being subject to call depth restrictions.
- Fixed certain code paths in the profiler not calling fflush on the output file.
- Fixed a small memory leak in the profiler’s writer thread.
- Fixed the profiler printing a misleading time went backwards debug message.
- New default GC bridge processor on Android
- The Android implementation makes use of a “bridge processor” which coordinates communication between the Mono and Java garbage collectors. There are three bridge processor implementations included, “old”, “new” and “tarjan”. In 4.6.0 the default has been changed from “new” to “tarjan”. This should result in performance improvements during GC for Android apps (or desktop apps using java.interop) that had not already selected the “tarjan” collector.
- FullAOT: Generic Value Type Sharing on x86-64
- The gsharedvt capability, which allows certain complex uses of generics to be used in FullAOT mode, is now available on the x86-64 ISA on Mac OS X and Linux-based platforms. This means gsharedvt is now available on all platforms where FullAOT itself is supported.
- New disable_omit_fp option for JIT/AOT compiler
- A new flag on the MONO_DEBUG environment variable (MONO_DEBUG="disable_omit_fp") disables an optimization used by the JIT and AOT compilers where the frame pointer is omitted from stack frames. This flag is likely to result in a small performance hit but can improve the ability of external debuggers to properly display function names, particularly when using AOT.
- Changed search path order for custom profilers
- When using a custom profiler library, the mono installation is now preferred over the assembly root or default library search path.
- Atomics fixes for ARM64:
- On ARM64, the code that Mono emitted for various atomic operations in the .NET Framework did not result in sufficient memory barriers. This could lead to all sorts of random bugs both in user and framework code. Mono suffered from a similar problem in the runtime C code due to bugs in the atomic intrinsics in GCC and Clang. All of these problems have been fixed, and Mono should be much more stable on ARM64 as a result.
- BUG FIXES:
- System.IO.File.GetAttributes now honors the “uchg” flag on OS X when determining file writability.
- The debugger now steps and breaks correctly when stepping into, over or out of a function which recursively calls itself.
- When using XML configuration files, a broader set of configuration section types is now available, including System.Configuration.DictionarySectionHandler.
- Exceptions can now be serialized using SerializeObjectState.
- Some issues with building on Windows have been addressed.

New in Mono for Windows 4.4.0 (Jul 28, 2016)
- IN DEPTH:
- Class Libraries:
- Our build system has been reconfigured to become a 4.x setup, as opposed to 4.5 only and it’s now tracking .NET 4.6.1 APIs.
- Targeting earlier .NET profiles happens via so-called reference assemblies, which we introduced in Mono 4.0.
- To make it more clear that these are just used for compilation and not during runtime (they contain only metadata, no actual method IL), we renamed the profile folders in /lib/mono/.
- WCF:
- WebHttpBinding must use http scheme in case when SecurityMode == WebHttpSecurityMode.TransportCredentialOnly
- RUNTIME:
- Embedding API:
- The embedding API now has the following additions:
- mini_parse_debug_option allows embedders to set debug options programatically, without going through the MONO_DEBUG environment variable.
- Bitcode:
- It is now possible to configure the runtime to generate LLVM bitcode when passing the --with-bitcode option to configure. This mode of operation avoids certain low-level optimizations that require assembly code to be used and instead limits the runtime to use constructs that can be expressed entirely in bitcode mode. This is designed to support scenarios where you want to use LLVM to drive the entire compilation process.
- Unmanaged Thin Locks:
- This avoids allocation of new MonoThreadsSync structures for the typical cases of shallow nesting of uncontended locks. The necessary information (owner, nest and status bits) is embedded in the synchronisation field of a MonoObject. The lock is inflated when the nest overflows or when there is contention on the lock.
- This greatly improves performance (over 10 times) for the case of locking a lock only a few times, due to the inflation avoidance. It also improves performance up to 25% for the case of locking a thin lock. A decrease in performance (up to 3 times slower) can happen for the case of repetitive nesting of a lock, due to the need of a CAS at each entry/exit.
- libmono now defaults to SGen
- The libmono library now defaults to using Mono with SGen, previously, it defaulted to Boehm.
- FullAOT: Generic Value Type Sharing improvements
- More code is now shared with Value Type sharing and we no longer generate shared wrappers for method signatures as those are not needed.
- Garbage Collector:
- This release contains a new mode of operation for Mono’s SGen garbage collector as well as many performance optimizations,and memory usage and throughput optimizations
- Cooperative Mode:
- Mono has historically used garbage collectors that can run at any time, that is, when a garbage collection is triggered, the GC system stops all threads preemptively and performs a garbage collection.
- This is a behavior that we inherited from Boehm’s GC which was great in the early days of Mono, as it allowed us to get a working garbage collector in no time, but also made the garbage collector harder to debug.
- We have introduced a new cooperative configuration to our garbage collector that makes it easier to debug garbage collector related problems and reduces the operating system specific requirements to have a functioning garbage collector.
- This mode can be enabled by setting the MONO_ENABLE_COOP environment variable.
- Implement Thread Priority Setting:
- Implement a SetPriority/GetPriority facility for real-time threads: if mono is executed using the SCHED_RR policy, we will map POSIX priorities to .NET priorities. Under this policy a thread running under this policy which uses the SetPriority API will have its priority remapped and a call to pthread_setschedparam() made to change its priority.
- For a sample program that shows how to run a Mono application without requiring all root privileges other than the CAP_SYS_NICE capability which enables priority manipulation see the thread-priority page
- LLVM Only Mode:
- It is now possible to use the Mono runtime in LLVM-only mode. This mode avoids the use of any assembly optimized code, or the mixed mode of Mono+LLVM. This is used to generate standard LLVM bitcode.
- This comes at the expense of some performance optimizations that are not possible to express with stock LLVM.
- Concurrent GC:
- We continue to improve the concurrent capabilities of the garbage collector, among those we enabled cementing for it, and tuned various parameters of nursery collection and improved the diagnostic capabilities of the concurrent GC.
- GC Handles:
- We have made the implementation of GC handles lock-free. The previous implementation would take a lock every time a GC handle was accessed (e.g., with WeakReference.Target or WeakReference.IsAlive). Removing this locking improves the performance of these operations by orders of magnitude—particularly on OS X, where locking is costly.
- We now provide universal (32/64-bit) binaries in our OS X package. 32-bit is still the default Mono executable on the terminal; For 64-bit use mono64 or mono --arch=64.
- Profiler:
- We are now annotating our GC roots, so the profiler can get better visibility into the nature of objects that keep objects alive.
- Threadpool:
- We no longer use the sparse array for the threadpool, as for many thread it would slow down some operations.
- Debugger:
- The soft debugger now allows nested invocations to take place.
- PowerPC:
- The PowerPC backend has been updated to support big endian systems.
- Process API:
- Refactored the Process API (FIXME: Marek, what was the source of this?)
- C# Compiler:
- Null operator (?.) has been implemented for dynamic expressions.
- experimental flag
- The language version future has been renamed to experimental
- IKVM Updated:
- We have updated IKVM to support 4GB output files.
- Portable Class Libraries:
- Introduced support for the PCL v3 contracts
- Platforms:
- Adds support for WatchOS, armv7k and new Android M.
- Named events and semaphores:
- The support for sharing named events/semaphores etc. between processes (MONO_ENABLE_SHM) has been removed. This feature was very complicated to implement on POSIX system and the implementation was very brittle and a constant source of bugs/problems. A possible replacement is to use the similar POSIX functionality in the Mono.Posix assembly.
- Reflection:
- Major upgrade to Reflection APIs, it implements many features that we never used in the past, but that are required to run Roslyn (FIXME: add more details).
- IL Assembler:
- Adds support for {auto} and legacy library. Those were added as no-ops to enable assembling the CoreCLR IL test suite.
- MICROSOFT SOURCE CODE ADOPTION:
- System:
- Adopted WebUtility class
- Adopted AuthenticatedStream class and family.
- Adopted AddressFamily
- Adopted IOControlCode
- Adopted IPPacketInformation

- FIXME: pull the list
- TOOLS:
- csharp:
- The interactive C# shell now implements code completion by showing a popup on the screen instead of using the Bash-style results.
- Code completion is also triggered by the “.” character, which is convenient in many cases, in addition to the existing TAB.
- CODE COMPLETION IN CSHARP:
- mdoc:
- Improved the rendering of Platform enumerations for platforms like iOS where we are interested in when an API was first introduced, not all the platforms that also support it.
- IMPROVED THE HANDLING OF GENERIC METHODS:
- mdoc - New options:
- New -api-style parameter and -multiassembly parameters can be used to update documentation in scenarios where we want to maintain a single XML API, but target slightly different source assemblies (like we have to do for Xamarin.iOS’s classic and unified, or iOS, tvOS and WatchOS).
- The new multiassembly option lets you run mdoc update on assemblies that contain the same types. This can come into play when you have a set of assemblies that run on different platforms, with a slightly differing API surface area on each platform (for example: tvOS, watchOS, iOS); in th`is case you can maintain all of the documentation in a single set of XML documents.
- With this option enabled, an AssemblyInfo node will be added for every assembly that a type is found in, in addition to every member. While this may seem verbose, it’s really the only way to capture the information about what assemblies a given type or member can be found in.
- mkbundle:
- Now supports the --quiet flag to prevent diagnostics messages from being printed out.
- xbuild:
- The xbuild command now defaults to XBuild 14.0 instead of 12.0. This means .csproj project files that use ToolsVersion=”14.0” (such as those created by Visual Studio 2015) or that target .NET 4.6 now build without warnings.
- Roslyn support: It now copies the Portable PDB files generated by the Roslyn compiler to the output directory.
- babysitter:
- This new script replaces GNU timeout and is intended to be used by automated builds of Mono on Jenkins or other continuous build systems. In addition, it:
- Logs machine readable output about each test suite (as line-delimited json)
- If the test suite uses NUnit, can detect if a test case failed or crashed (terminated mono in mid-test), and retry unsuccessful tests (up to a limit).

New in Mono for Windows 4.2.1 (Nov 17, 2015)
- Highlights:
- More adoption of Microsoft’s open source code
- Support for PPDB debugging format
- New threadpool implementation
- Runtime optimizations
- Extensive bug fixing
- Runtime:
- Portable PDB files
- Mono’s runtime can now consume debug information encoded in the new Portable PDB file format.
- The Portable PDB (Program Database, or PPDB) format describes an encoding of debugging information produced by compilers of Common Language Infrastructure (CLI) languages and consumed by debuggers and other tools. And most importantly, it is fully documented.
- At the same time, newer versions of Microsoft’s Roslyn compilers are now able to produce PPDB files so it is now possible to use Roslyn compilers and have the Mono runtime use their debug information.
- The PPDB format is under active development, while Mono currently implements support for the latest edition of the format, it is possible that the format might still change.
- Layout Changes for Nested Structures:
- Nested structs used to be aligned to sizeof (void *) so they looked blitable, but didn’t match their native layout.
- This caused all sort of issues when doing interop.
- We now align them following ABI rules, which should fix a lot of issues.
- This is a breaking change to those already native interop and relying on the wrong layout calculations done by the runtime.
- Delegate Internals Updated:
- Change how delegates work internally from using a reverse linked-list to an array.
- This will be faster and allow us to enable the fast vcall thunk for delegate invoke.
- Static Compilation (FullAOT)
- We now collapse enum to primitives and ref types to object and share based on that.
- So for example a KVP will share the implementation code with KVP
- Stacktraces on re-throws:
- We have changed the stack trace behavior on rethrows.
- This is a merge of https://github.com/mono/mono/pull/1668
- Most commonly, an exception is thrown immediately after it is constructed and processed without being saved. It is possible to catch exceptions, save them to variables, and throw them again at a later time.
- When this type of exception is caught in .NET, the StackTrace on the exception object refers to the location where the exception was last thrown from. In Mono, we were giving it the location that the exception was first thrown from. This fix makes Mono more closely behave like .NET.
- ProcessInfo.Modules:
- ProcessInfo.Module returns the list of loaded modules, we now are able to return the address of any of the assemblies loaded with mmap(), previously this functionality was not available.
- Microsoft’s ThreadPool:
- We have replaced Mono’s implementation of the ThreadPool with Microsoft’s implementation. It has many interesting properties in terms of how threads are started up and terminated, which was too aggressive previously.
- The new code is also simpler to maintain.
- Added ARM HFA support
- The runtime now supports the HFA calling convention on ARM architectures.
- SafeFileHandle
- We have extended the use of SafeFileHandle in the stack, in addition to file handles, we now use it for socket handles.
- Concurrent Sweep in the GC
- The purpose of this is to reduce pause times of major collections by making sweep completely concurrent.
- The first phase of sweeping is iterating through the block list, freeing blocks without live objects, and designating the others for lazy sweeping. This phase happened while the world was stopped. This makes it concurrent. The changes include the introduction of a very simple thread pool abstraction (currently supporting only a single thread) that unifies concurrent marking, jobs when scanning roots, and concurrent sweeping.
- Read more details and charts
- Dropped support for external Boehm libgc
- The Mono runtime is no longer able to use an externally compiled Boehm libgc library.
- Support for Direct internal calls:
- The Mono runtime can now perform direct calls to internal calls from managed code, without requiring icall wrappers.
- The Mono runtime no longer raises exceptions directly, but instead uses the mono_set_pending_exception which allows us to remove the overhead of calling an internal call. This improved performance is mostly visible with runtime intrinsics that are invoked by the generated managed code, and shows up in particular in micro benchmarks.
- New thread suspend machinery:
- We reworked suspend code to be based on a state machine and eliminate known races in the process.
- Profiler:
- This release contains major upgrades to the profiler infrastructure to support tools like the Xamarin Profiler whose UI required more information than we were previously providing, or to make it simpler and faster for the profiler to consume and process the data.
- Microsoft Source Code Adoption:
- This is the second release of Mono that replaces various components of Mono with code that was released by Microsoft under the MIT license in one of three places:
- Microsoft’s ReferenceSource drop
- Microsoft’s CoreFX
- Microsoft’s CoreCLR
- While Microsoft is working towards .NET Core: a redistributable and re-imagined version of .NET, the project remains a work in progress. Mono at this point continues to provide an API that tracks the .NET desktop/server version.
- This means that most of the code that we have integrated comes from the ReferenceSource drop. In the future, we will deliver a “Mono Core” along the same lines of .NET Core to allow the use of the Mono runtime with the new library distribution system that is being developed with CoreFX.
- In this release, we have either ported components that were either incomplete or buggy in Mono and were relatively easy to port to Mono. There is much more to be done in this area. If you are interested in tracking those efforts, check the project status.
- Mono ships now with a subset of the referencesource that have been adjusted to work with Mono’s class libraries or have been updated to be cross platform.
- Changes made to Microsoft’s reference source code are published under Mono’s github organization fork at http://github.com/mono/referencesource
- System assembly:
- The following components in the System assembly were replaced with Microsoft’s implementation, with some small changes to make the code portable to Unix:
- System.CodeDom implementation
- Parts of System.Diagnostics (excluding the components that are tied with the Mono runtime)
- Small parts of System.Net.NetworkInformation
- Parts of System.Net (HTTP Cookie handling)
- mscorlib assembly:
- Around 500 .NET types were replaced with the Microsoft implementation, with small changes made to make Microsoft’s code portable.
- Some themes in this release include:
- Replacing some of the key types in the System namespace
- Continued our work to replace large chunks of the globalization stack in Mono with Microsoft’s implementation
- Portable parts of System.IO
- Large parts of System.Reflection, those that do not depend on Mono runtime internals.
- Large parts of System.Resources
- The portable parts of System.Runtime.InteropServices
- The portable parts of System.Security.Cryptography
- Most of System.Text
- Most of System.Runtime.Serialization
- The threadpool
- Most of SafeHandles
- LINQ:
- The types from System.Linq in the System.Core assembly have now been completely replaced with Microsoft’s implementation.
- System.Data assembly:
- The cross-platform parts of System.Data have been replaced with Microsoft’s implementation of System.Data.
- The System.Data.SqlClient API which implements the connectivity to SQL server continues to be Mono’s implementation, as Microsoft’s implementation is too tied up to Windows specific code.
- While we had an implementation of System.Data.OleDb in the past, which depended on Gnome’s GDA library, it has not been operational in many years, so we have removed the implementation, and added in its place a Windows specific version from Microsoft (that means, we do not have a cross platform OleDb, but we did not have a working one to begin with).
- System.Runtime.Serialization assembly:
- Switched most of this assembly to the Reference Source code. We have made a few changes that allow this assembly to be used with systems that do not allow dynamic code generation (iOS, PlayStation and Xbox)
- System.Xml and System.Xml.Linq assemblies:
- We have replaced Mono’s System.XML implementation with Microsoft’s version.
- For systems that do not allow dynamic code generation (iOS, PlayStation, Xbox), the XmlSerializer continues to be Mono’s old XmlSerializer.
- Replaced Assemblies with Microsoft code:
- The following assemblies are now mostly based on Microsoft’s ReferenceSource code, with small changes to make them cross platform, or otherwise be integrated into Mono’s build system:
- System.Data.DataSetExtension
- System.Runtime.DurableInstancing
- SMDiagnostics
- System.ServiceModel.Internals
- System.Web.Services
- Tools:
- mono-symbolicate
- New tool that is a tool that converts a stack trace with :0 into one with file names and line numbers.
- MonoDoc:
- The mdoc command has been updated to better match generic arguments when updating your existing documentation.
- We no longer ship all of Lucene.Net, instead we only ship the parts that MonoDoc actually uses.
- mkbundle:
- Now takes a --dos2unix[=false] parameter which controls whether mkbundle should use the dos2unix command on the resulting output.
- Mono Linker:
- The Mono linker adds support for PCL type forwarders, making the linker PCL friendly.
- The linker also now supports descriptor files embedded into assemblies being linked. This allows developers to embed linker description files that can instruct the linker how to link an assembly without requiring the end user to know about the internals of an assembly.
- Adds support for linking security declarations.
- It also fixes support for generics and linking and improves the linker performance.
- mdbrebase:
- The tool now has a silent mode
- mono-api-html:
- Now uses CSS for coloring API diffs, instead of old school HTML.
- It now ignores non-important attribute differences
- Properly colorize removed types (as red).
- Print ‘NotSerialized’ field attribute change (as not breaking).
- Ignore ‘HasSecurity’ and ‘PInvokeImpl’ method attribute differences.
- Render property indexers (and detect name change in property indexer parameters).
- Improve debug spew to print proper method/field attributes.
- Renders generic parameter constraints
- ilasm
- Implement support for many undocumented features in ilasm
- xbuild
- Improves the Visual Basic compiler support (requires Roslyn based compiler, available separately).

New in Mono for Windows 4.0.0 (May 1, 2015)
- FLOATING POINT OPTIMIZATIONS:
- Mono has historically chosen to use the highest possible precision for all floating point operations. This means that both 64-bit math and 32-bit math were done with the highest precision available.
- But performance sensitive code that might not need high precision was negatively impacted.
- With this release we are introducing support for performing 32-bit floating operations using 32-bit math. This produces faster code at the expense of fidelity. This mode of operation can be enabled with the -O=float32 option. This option currently needs to be enabled manually, it is not part of the -O=all options.
- C#:
- Mono’s C# compiler now defaults to C# 6.0
- The compiler will now avoid generating a GUID each time it builds, generating identical builds across recompilations. Following the steps of Roslyn’s new default.
- MICROSOFT SOURCE CODE ADOPTION:
- This is the first release of Mono that replaces various components of Mono with code that was released by Microsoft under the MIT license in one of three places:
- Microsoft’s ReferenceSource drop
- Microsoft’s CoreFX
- Microsoft’s CoreCLR
- While Microsoft is working towards .NET Core: a redistributable and re-imagined version of .NET, the project remains a work in progress. Mono at this point continues to provide an API that tracks the .NET desktop/server version.
- This means that most of the code that we have integrated comes from the ReferenceSource drop. In the future, we will deliver a “Mono Core” along the same lines of .NET Core to allow the use of the Mono runtime with the new library distribution system that is being developed with CoreFX.
- In this release, we have ported components that were either incomplete or buggy in Mono and were relatively easy to port to Mono. There is much more to be done in this area.
- Mono ships now with a subset of the referencesource that have been adjusted to work with Mono’s class libraries or have been updated to be cross platform.
- Decimal:
- We have replaced Mono’s System.Decimal implementation with Microsoft’s version. This fixed a couple of formatting bugs. While Mono’s code did not have any major bugs, Microsoft’s implementation is more efficient and is actively maintained. Fixing bugs in System.Decimal was always difficult.
- Assorted Microsoft Classes Imported:
- These are some highlights of code imported from Microsoft (smaller bits like attributes, enumerations, event arguments, exceptions or other simple bits are not shown):
- The following namespaces have been entirely, or almost entirely replaced with ReferenceSource code:
- System.Collections
- System.Collections.Concurrent
- System.Collections.Generic
- System.Collections.Specialized
- System.ComponentModel
- System.ComponentModel.Design
- System.Diagnostic.Contracts
- System.Linq
- System.Linq.Parallel
- System.Text.RegularExpressions
- System.Runtime.CompilerServices
- System.Threading.Tasks
- Partial changes:
- System:
- ArraySegment
- BitConverter
- Boolean, Byte, Char, Decimal, Int16, Int32, Int64, SByte, UInt16, UInt32, UInt64,
- Convert
- DateTime, Decimal
- Guid
- Lazy
- Random
- TimeSpan
- Version
- System.Collections.Generic
- HashSet
- Mostly replaced
- System.Diagnostics.Contracts
- System.Globalization
- Entire calendar stack
- DaylightTime
- TextInfo (replaces text categorization tables, replaces it with .NET which is half the size)
- System.IO
- BufferedStream
- Stream
- MemoryStream
- StreamReader, StreamWriter, StringReader, StringWriter, TextReader, TextWriter
- System.Linq.Expressions
- DynamicExpression, ExpressionVisitor
- System.Net
- Cookie, CookieCollection, CookieContainer,
- FtpWebRequest
- WebClient
- System.Text
- Bring the non-code page encoders
- System.Threading (about 60% replaced)
- GARBAGE COLLECTOR:
- The Xamarin performance team has been fine tuning Mono’s SGen garbage collector.
- DROPPED SUPPORT FOR OLD FRAMEWORKS:
- Reference Assemblies:
- We no longer build the reference assemblies for the .NET 2.0, .NET 3.5 or .NET 4.0 APIs, we now ship binaries of the reference assemblies (API contracts, without any actual executable code in them).
- Mono will now only build the .NET 4.5 assemblies as well as the mobile-based profiles.
- Note: You can still run assemblies compiled for earlier .NET profiles on Mono, there’s no need to recompile them (they’ll just run on the .NET 4.5 assemblies instead).
- Npgsql:
- Mono no longer distributes the Npgsql driver. Developers that need it will be better served by using the actively maintained Npgsql driver from this site
- EntityFramework:
- The version of EntityFramework that we shipped had not been updated in a long time, and users are currently getting EntityFramework with NuGet.
- OTHER FEATURES:
- Added LLDB scripts to assist developers debugging the runtime with LLDB
- MonoIO method and classes now uses SafeHandles
- System.Net.NetworkInformation implements more features on more platforms
- FINE TUNING:
- We now inline copies of structures up to eight machine words, up from the previous five. Values larger than that still call memcpy to complete the operation.
- We now support returning floating point structures by value and can better pack floating point structures.
- LLVM is now given more lattitude to inline generated code.
- More methods can be compiled with LLVM on ARM. This helps many methods that passed large structures as parameters.
- All atomic methods in the framework are now recognized by the JIT as intrinsics and are inlined as specialized code on platforms that support it. This includes all methods on Interlocked and Volatile, as well as the MemoryBarrier, VolatileRead, and VolatileWrite methods on Thread.
- On x86-64, Thread.MemoryBarrier is now implemented with mfence instead of lock add rsp, 0. Also, Interlocked.Exchange is now implemented with xchg [dst], val instead of the overly expensive lock cmpxchg [dst], val loop we previously emitted.
- For atomic methods with acquire/release semantics, we now emit memory barriers with those semantics instead of the overly strong sequentially consistent kind.
- The Enum.HasFlag method is now significantly faster for the most typical usage pattern, which is a.HasFlag (b) where a and b are the exact same type. We transform such calls to an actual bitwise AND and skip all the heavy reflection normally done in the method. This is about 60x faster than before. Additionally, the regular implementation of the method which is only used for rare/pathological cases is now 4x faster than before.
- The JIT now avoids emitting pointless move opcodes when the destination register is the same as the source register.
- The runtime now supports performing calls directly to some internal calls (those that are known not to raise exceptions). This eliminates the overheads of wrapper methods, both a performance and memory usage benefit.
- When precompiling your assemblies, you can use the “direct-calls” option to enable this feature.
- MONOP TOOL:
- The monop tool now uses IKVM.Reflection to load assemblies, so it will work with foreign mscorlibs. In addition the -xi and -xa flags can be used to search types in the Xamarin.Android and Xamarin.iOS frameworks.
- MUSL LIBC:
- There is now rudimentary support for building Mono with the musl libc on Linux. To do this, pass --disable-boehm --without-sigaltstack to configure.
- C99 SWITCH:
- The runtime now requires a compiler with C99 support. For Windows users, this means that Visual Studio 2013 is now required to build Mono. Cygwin or MinGW users should not be affected by this change. Similarly, compilers on most Unix platforms have supported C99 for a long time.

New in Mono for Windows 3.12.0 (Jan 14, 2015)
- Highlights:
- Major performance and memory consumption improvements on SGen.
- Improve the heuristic of the ThreadPool to maximize efficiency and minimize the number of Threads
- Experimental preview on new Windows installer
- Garbage Collector:
- Reorganized how major heap blocks are manipulated for increased efficiency of the major collection.
- Reduced memory consumption by better sizing of allocation buckets.
- Switched to a simpler heuristics for major heap sizing that is more stable and avoid unexpected spikes.
- Removed the parallel collector, it was an experimental feature that did not provide an effective speedup. It will be brought back in the future with a functioning design.
- Removed the fixed heap configuration, it was an experimental feature that did not deliver enough of a performance improvement. Removed for the additional complexity.
- Canaries are now supported for the nursery. Canaries is a lightweight debugging tool for detecting memory corruption. Enable it with the new “nursery-canaries” option in the MONO_GC_DEBUG environment variable.
- Threadpool:
- Switched to adaptative hill climbing for sizing the pool. This fixes the cases where the old algorithm would cause thrashing by spinning too many threads.
- The supervisor thread now goes into deep sleep when no new jobs are submitted for a while. This should save power on targets running on batteries.
- Runtime:
- Implement the new suspend machinery on Windows, amd64 and arm. The new machinery is known to be more reliable and results in significantly less hangs when using advanced threading features of the platform.
- The minimum version support of Windows is now WinXP SP2, it was Windows 2000 before. (Wait what?)
- Tooling:
- Debugger support for 64bits Windows.
- Multiple fixes in the profiler to make statistical sampling reliable and functional on unix targets without kernel assisted sampling.
- Performance:
- X86 code now generate pushless code. This is faster on modern cpus and produces smaller unwind information.
- Reworked internal runtime locking to do less work under hot locks and do more optimistic metadata loading.
- Class Libraries:
- OS X now uses an experimental FileSystemWatcher that relies on kqueue. It works and doesn’t require polling.
- Packaging:
- New experimental Windows installer available. It’s a technical preview so any feedback is welcome.
- BUG FIXES:
- Runtime:
- Avoid asserts on shutdown when the appdomain unload callbacks are called on the debugger thread during shutdown. Fixes #24342.
- Fix the calculation of the epilog size for EH info. Fixes #24577.
- Fix a class initialization race which happens if a class initializer initializes a got slot before it finishes running. Fixes #23242.
- Fix OP_LOCALLOC on arm so it correctly adjusts sp with the param area size even if the size is large. Fixes #24221.
- Disable the extension of i8/i16 arguments to i32 on arm64, since the ios calling convention passes them differently than i32. Fixes #22800.
- Use NULLIFY_INS () to nullify instructions and use MONO_INST_NEW to create phi node instructions to avoid asserts in the spill pass. Fixes #24006.
- Rewrite the way direct calls are made between llvm methods. Previously all calls were made to plt entries and the plt entry symbols were aliased to point to the corresponding method if the method was directly callable using the .set assembler directive. This doesn’t seem to work with newer LLVM/CLANG versions, so do this completely on the LLVM side using Value::replaceAllUsesWith (). Fixes #23976.
- Make process handles non-shared. Fixes #23423.
- Fix the return of vtypes containing a single fp member from pinvoke methods on OS X/x86. Fixes #23813.
- Fix an SRE assert. Fixes #19039.
- Implement 5dbf97e66057f8626c53fcea30f1988d6627e5a2 for calls made from NEWOBJ too. Fixes #23557.
- Make each CASTCLASS_CACHE patch unique by generating a unique identifier from the method index and an per-method counter. Fixes #23478.
- Disallow generic classes with explicit layout. Fixes #23438.
- Add an option to make debugger invokes virtual. Part of the fix for #23385.
- Allow renaming of threadpool threads. Fixes #23206.
- Fix the unregistration of our exception handler on Windows. Fixes #23221.
- Make calls from gshared to gsharedvt sharable methods indirect since otherwise at runtime we might find an instantiation and we cannot patch the call, leading to performance problems. Fixes #23021.
- Allow the SIZEOF opcode in gsharedvt code if it doesn’t reference a gsharedvt type. Fixes #22711.
- Fix mono_marshal_free_ccw (). Fixes #22414.
- Class Libraries:
- Fixes DbEnumerator current property to clone read data. Fixes #24452
- Allow sending of text data longer than 4000 characters by using a different column type. Fixes #21172.

- Improved BlockingCollection.AddAny. Fixes #22775.
- Implement KnownTypes for DataContractJsonSerializer. Fixes #23058
- HttpQSCollection.ToString now url encodes values. Fixes 22557.
- Call SetupRequestAsync only after ContentType changes. Fixes 19529.

- Use TZ transitions when AdjustementRules are ignored. Fixes 23170.
- Timespan ticks formatting rewrite. Fixes #23376
- Improved Json deserialization of floating-point numbers. When DataContractJsonSerializer was created from type object, deserialization of floating.point numbers was not possible. Fixes 21583.
- Test Json deserialization of a floating-point number as object. Covers 21583.
- Rss20ItemFormatter.ReadFrom now sets Id when guid is PermaLink. Fixes 23262.
- fix bug #23318 - XComment.ToString() accepts “invalid” values.
- Uri made from UNIX path and RelativeOrAbsolute is now relative. Fixes 22954.
- UriParseComponents no longer decodes ‘@’ in UserInfo. Fixes 23246.
- Update en-NZ designators. Fixes #22212
- Update to my last fix for bug #22129.
- Copy out/ref parameters on async call; bug #22129.
- If not specified assume that array items are nullable. Fixes #19012.
- Added optional serialization based on ShouldSerialize{V}. SerializationCodeGenerator and XmlSerializationWriterInterpreter will no longer serialize an attribute named {V} if its object has a method named ShouldSerialize{V}() that returns false. {V}Specified now is also checked to be true before serializating the attribute even if it is a property that is not settable. Fixes #1852.
- GMT DateTimeOffset is now properly parsed. Fixes #22851. GMT date formats set useutc to true, so now useutc is checked to init DateTimeOffset with a zero offset.
- Improved CalendricalCalculations fixed_from_dmy methods. Fixes #21930. In some cases fixed_from_dmy is used with the month parameter greater than the number of months of that year. Year is now incremented until month parameter is valid.
- Enumerate all subdirectories including the first one. Fixes #22857

- Unify handling of default ctor and zero. Fixes #22591
- Make SendAsync state free to handle recursive calls. Fixes #22724
- Actually fix #22179 to allow concurrent requests.
- DateTime.Parse now handles unlimited number of fractional digits. This change was made because .NET can parse ISO8601 format with an unlimited number of fractional digits. Fixes #22417.
- Added test ISO8601FractionalDigits. Covers #22417.
- Delay reflection hit to actual execution point. Workarounds #22522
- Update RequestMessage.RequestUri.AbsoluteUri after redirect. Fixes #22383
- Catch exceptions thrown by SerialPortStream.Dispose () when called from the finalizer. Fixes #15514
- KeyPairPersistence now tries to fix folder permissions. An exception is no longer thrown if the folder permissions can be fixed. Fixes bug 19274.
- C# Compiler:
- A pointer-type may be used as the type of a volatile field. Fixes #23770
- Correctly identify constant switch section when value match is not section start. Fixes #23475
- Check for true/false user operators on unwrapped nullable type. Fixes #23199

- Use ToolPath when building ToolTask execution path. Fixes #22981
New in Mono for Windows 3.10.0 (Jan 14, 2015)
- Highlights:
- Implemented System.IO.Compression.FileSystem.
- Uri now implements the .NET 4.5 behavior, it can be reverted to the old behavior in the same way by setting the System.Uri::s_IriParsing static field to false.
- Performance:
- Remove unnecessary locking from core metadata parsing functions.
- Avoid cache thrashing of locals array when looping over enumerator.
- Known Issues:
- The OSX packages have an invalid libgdiplus library that affects users of System.Drawing that requires it to work.
- This specially affects Xamarin.Mac users that fit the following criteria:
- Uses Xamarin.Mac Classic (Unified is unaffected).
- Uses the subsets of System.Drawing that use libgdiplus.dylib internally
- System.Drawing.RectangleF, PointF, Colors are unaffected
- System.Drawing.Bitmap, and font for example are affected
- The symptom of the problem is your application failing with: “System.TypeInitializationException: An exception was thrown by the type initializer for System.Drawing.GDIPlus —> System.Exception: GdiplusStartup”

- Fix support for unaligned offsets in the store_membase_imm opcodes. Fixes #23267.
- Fix the lookup of nested types which have a namespace. Fixes #21653.
- Increase some opcode sizes. Fixes #23026.
- Always pass the imt arg to interface calls in gsharedvt methods. Fixes #22624.
- Store the epilog length in MonoArchEHJitInfo instead of encoding it in jinfo->unwind_desc, since the latter can overflow for methods with large epilogs. Fixes #22685.
- Add a mono_thread_detach_if_exiting () public api function which can be called by embedding code to detach the runtime if the code is running from a pthread dtor. Fixes #21164.
- Fix yet another native types problem. Fixes #22053.

- Fix enum->int casts in gsharedvt code. Fixes #21893.
- Don’t assert when loading a generic methodspec with 0 arity. Fixes #19097.
- Avoid asserting when a cattr cannot be loaded. Fixes #21653.
- Avoid making generic calls from gsharedvt methods normally, go through the rgctx infrastructure instead. Fixes #21677.
- Class Libraries:
- Fix Uri UserInfo parsing. Fixes 23246.
- Update RequestMessage.RequestUri.AbsoluteUri after redirect. Fixes #22383.
- Fixes XContainer attempt to create a XNode from a null value. Fixes #20151.

New in Mono for Windows 3.8.0 (Jan 14, 2015)
- Highlights:
- Runtime performance counters have been integrated into the profiler allowing the performance counter information to be surfaced to profiling tools and in particular Xamarin’s upcoming profiler.
- The profiler now produces backtraces for statistical mode. The profiler’s tracing mode now works on ARM.
- We now distribute nuget on mac.
- Debugger:
- The debugger now support line and column ranges. pdb2mdb supports it. Note: the rest of our toolchain still needs to be updated.
- The debugger now supports changing the current line in the top frame.
- Lots of bugfixes and performance improvements.
- The debugger now support reading simple properties without calling their getter, this is done by having a lightweight IL interpreter for small pieces of code. This allows more properties to be inspected while the process is completely stopped and without having to temporarily resume execution of the target to execute the property code.
- Added buffered response mode to improve network efficiency on high latency links such as USB.
- Garbage Collection:
- The GC bridge got a lot of performance work. There are now two new modes that can significantly improve some workloads.
- Class libraries:
- Multiple http stack improvements: some leaks in the stack have been fixed, as well as solving some long-standing bugs involving asynchronous operations and proxies. We have introduced a more comprehensive test harness to ensure that those bugs do not surface again.
- System.IO.Compression is now implemented
- System.Security.Claims is now implemented. It resides in the System assembly (existed before in the Identity stack, but now we track the new home from the .NET 4.5 API).
- Performance:
- Reworked locking to drop a hot lock in method lookup.
- Use fine grained locking instead of a big hot lock.
- Better hashing of some runtime internal items to avoid some corner-case slowdowns with generics.
- Profiler:
- The profiler is now able to produces backtraces in statistical mode.
- Added periodical flushing that should help interactive users. This means that the profiling will send data over the profiling even if the application is not currently sending data (this is there to support the upcoming new profiler UI).
- It now collects and reports performance counter information. See mprof-report’s man page.
- Misc:
- Fixed the handling of the volatile. CIL prefix.
- We now distribute IKVM’s ikdasm tool. This is a reliable disassembler that does not have the limitation of monodis of requiring a complete set of assemblies that are compatible to disassemble. This will disassemble even files that do not have their dependencies available.
- Optimized EqualityComparer for more types.
- Mono.Unix.Native.Syscall.getxattr() can now return Errno.ENOATTR on OS X.
- Our msbuild implementation can now build Project K and Roslyn

- The debugger now support line and column ranges. pdb2mdb supports it. Note: the rest of our toolchain still needs to be updated.
- The debugger now supports changing the current line in the top frame.
- Lots of bugfixes and performance improvements.
- The debugger now support reading simple properties without calling their getter, this is done by having a lightweight IL interpreter for small pieces of code. This allows more properties to be inspected while the process is completely stopped and without having to temporarily resume execution of the target to execute the property code.
- Added buffered response mode to improve network efficiency on high latency links such as USB.
- Garbage Collection:
- The GC bridge got a lot of performance work. There are now two new modes that can significantly improve some workloads.
- Class libraries:
- Multiple http stack improvements: some leaks in the stack have been fixed, as well as solving some long-standing bugs involving asynchronous operations and proxies. We have introduced a more comprehensive test harness to ensure that those bugs do not surface again.
- System.IO.Compression is now implemented
- System.Security.Claims is now implemented. It resides in the System assembly (existed before in the Identity stack, but now we track the new home from the .NET 4.5 API).
- Performance:
- Reworked locking to drop a hot lock in method lookup.
- Use fine grained locking instead of a big hot lock.
- Better hashing of some runtime internal items to avoid some corner-case slowdowns with generics.
- Profiler:
- The profiler is now able to produces backtraces in statistical mode.
- Added periodical flushing that should help interactive users. This means that the profiling will send data over the profiling even if the application is not currently sending data (this is there to support the upcoming new profiler UI).
- It now collects and reports performance counter information. See mprof-report’s man page.
- Misc:
- Fixed the handling of the volatile. CIL prefix.
- We now distribute IKVM’s ikdasm tool. This is a reliable disassembler that does not have the limitation of monodis of requiring a complete set of assemblies that are compatible to disassemble. This will disassemble even files that do not have their dependencies available.
- Optimized EqualityComparer for more types.
- Mono.Unix.Native.Syscall.getxattr() can now return Errno.ENOATTR on OS X.
- Our msbuild implementation can now build Project K and Roslyn
- Optimized EqualityComparer for more types.
