    The Open Toolkit library is a fast, low-level C# wrapper for OpenGL

    ...It runs on all major platforms and powers hundreds of apps, games, and scientific research programs.

It is the ideal starting point if you want to write a game or scientific application from the ground up. The OpenGL specification specifies exactly what the result/output of each function should be and how it should perform. It is then up to the developers implementing this specification to come up with a solution of how this function should operate. ...
