OpenGL4Net
Simple OpenGL 4.3 wrapper for .NET platform
... (probably BSD).
OpenGL4Net is a simple wrapper of OpenGL 4.3 for .NET platform. The main idea of the library is to keep the syntax as close as possible to the C style and on the other hand, provide some overloaded functions that simplifies the development of .NET application.
The library also contains some helper classes to make a development really fast (e.g., class RenderContext for opening the OpenGL context; or class Program for loading, compiling and linking shaders)
