I've dipped my hands into C#. Unfortunately they don't have the DirectX SDK at the school so I'll have to play around with that at home. I might even just use the .NET framework to make a multiplayer asteroids clone (without using Direct3D, just the .NET framework). I don't know, we'll see when I get there.
Karl worked on rBlocks a bit and we've decided to make a new release of it with a new title. Any suggestions on a good tetris clone title?
... In other news, GDNet++.
