Alternatively there is another C# wrapper package for OpenGL: OpenGL DotNet. Works great for me! Check it out at http://www.taylaninan.com/opengl-dotnet.php .
It wraps OpenGL up to version 4.4 and supports over 550+ OpenGL Extensions. It also supports GLU, GLUT, FreeGLUT, DevIL (Developer's Image Library), ILU and ILUT for DevIL.
It a low level API for the above libraries.
