That's good, because I plan on using C# and SDL.Net for my biggest game project yet. It's a really great language, the best I've worked with (well, at least for me anyways). SDL.Net is just as easy to use, and it was really easy to learn most of the essentials of it. However, I want to try making something big with them so I can get experience.
I'll probably be using it when I make the sequal to Stompy[lol]
Oh, and C# is awesome[grin].
