JigLibX is a C# port of the JigLib physics engine. Like many other C# middleware game libraries (e.g., Axiom) JigLibX is, in its first implementation, a port of a C++ library. However the goal for JigLibX Beta is to make the library "more .NET".As the engine is written entirely in C# it is particularly well-suited for integration with XNA and is already in use by some C#/XNA projects.
