Simple Injector

Simple Injector is a specially developed Dependency Injection library for .NET 4 and above that supports numerous frameworks and environments, including but not limited to Mono, Silverlight and Windows Phone. The DLL suite can be easily integrated with modern frameworks such as ASP.NET Core, Web API or WCF, for instance and the dependency injection pattern can be easily implemented with loosely coupled components.

According to the developer, the library packs a powerful set of features that support a vast array of advanced scenarios. Moreover, it can run in a medium or partial trust environment and supports code based configuration as well as built-in diagnostics services that allow you to identify numerous potential issues.

In addition to the extensive support, the library is optimized for concurrent and performance usage. Thanks to its lock-free design and thread-safe, it can scale linearly with numerous processors and threads. In fact, the estimated speed of resolving object graphs is comparable to the hard-wired object instantiation. As a result, you can stay focused on unit testing, bug fixing, implementing new features and other important aspects, since you no longer need to worry about the time needed to construct a graph object. At the same time, you are less likely to have to monitor the library performance or make adjustments to improve performance.
