Yesterday I've started playing around with this great project and I've ported some NeHe Lessons (2 to 12) for familiarization with the code. I tested on Linux (OpenSuse 11.2/Mono 2.6/OpenTK Trunk Version) and Windows XP through VirtualBox where I had some troubles with opengl32.dll, but I think that's a problem with VirtualBox driver.
For compilation in Visual Studio, F5 does the job. In MonoDevelop you must 'xbuild' in src directory, or copy the data directory to .bin/debug/.
I will continue to port the lessons and as soon I get some work done I'll post here.
Remembering that's a very basic starter kit only for OpenGL newbies.
