The North State Framework (NSF) is a robust, Microsoft .Net class library that simplifies creating highly-extensible, object-oriented code from a UML State Machine diagram. NSF provides true object-oriented classes that enable extensive reuse and maintainability through state machine inheritance and composition. Imagine being able to "plug" an existing state machine into another state machine, with a single line of code-that's the power of the North State Framework!

NSF provides a one-to-one mapping between UML State Machine diagram elements and library classes, so the implementation is a direct translation of the design, making code creation a simple process. Together with all the built-in utility classes for timers, threading, and tracing, this simplicity will enable engineers to efficiently develop highly maintainable code even for the most complex of the state machine designs.

NSF State Machine Features:
· States (Simple and Composite)
· Pseudo-States (Initial, Choice, Deep History, Shallow History)
· Transitions (with Event Triggers, Guards, and Effects)
· Events (Simple and Payload-Carrying)
· Reactions (Internal Transitions)
· Regions (for Concurrency)
· Fork Joins (Branching and Merging based on UML Fork and Join Constructs)

NSF Design Features:
· Inheritance
· Composition
· Threading
· Timers
· Trace Logging
· C# .Net

Here are some key features of "North State Framework":

· State machine support
· Class inheritance support for state machines
· Class composition support for state machines
· One-to-One mapping between state machine diagram elements and classes for ease-of-use
· Ability to easily modify resulting C# code
· Ability to modify portions of your design, without having to regenerate the entire application
· Utility classes for timers, threading, trace logging


Requirements:

· Microsoft .Net Framework 2.0


Limitations:

· Limited to creation of three state machines.
