OpenTK ("the Open Toolkit") is an advanced, low-level .NET/Mono library that wraps OpenGL, OpenCL and OpenAL. It is suitable for games, scientific applications and any other project that requires 3d graphics, audio or compute functionality.
It runs on Windows, Mac and Linux with accelerated 3d graphics.
There is an OpenTK "How To" program that comes with Cobra.
