Hi all I am completely new in OpenGL and I am using C# and in the http://nehe.gamedev.net/ I found that there is some tutorial lesson that didn't contain the equivalent C# Code or CSGL and I am wondering is they are missing coze .net cant implement some features in this tutorials or There is no one that implement that code yet and if they are all implemented where can I found them?

The reason is no one implemented the c# code for that "some" tutorial (be more vague pls). You can do the same stuff with c# or pascal or basic in opengl than with c++ and opengl.
