Exception in ProgramFactory, public static T Create<T>() when starting any of examples

Whenever I try to start any of the examples from tree list, a window with white rectangle on black background briefly shows and I get an exception

An unhandled exception of type 'System.Exception' occurred in ObjectTK.dll

ObjectTK 2.0 Checklist

Current tasks:

  • Add debug extension/tool.
  • Discuss texture implementations
  • Add embedded resource loading
  • Add .obj importer
  • Add some basic primitive vertex arrays
  • Add typed Shaders
  • Add 3D package
  • Figure out how to deal with extensions (like aniso filtering)

Pass Data to Fragment Shader.

I'm new to OpenGL. I played with the examples and noticed that I can't send data directly to the fragment shaders instead of that I need to send to the vertex shader then the vertex shader sends it to the fragment shader. Is this normal?

Shader compilation error

When I try to compile the shaders from the included exemples I get an error telling me that the version directive must be first statement.
I've looked at the code and it looks like some sort of line number reference is appended before anything and it seems to be the cause of the issue.
