I participated at XNA Pizza Night yesterday, and when there with the 4day game I made. We won!!… well at least some Pizza 
.
But it was really fun, and there where some amazing games there, including the Night’s Winner Vizati, who took home a xbox 360.
I’ve been learning basic thing about the usage of .Net Framework. Basically making small WinForm Application 
. I like it. But I think it’s visually limited compared to Qt.
Qt is cool, but now I don’t have the time to nor the will to get back to it where I left…
I’ll keep on with WinForms and then maybe to WPF…
I recently found that C# is the best thing to learn.
1 – Microsoft supports it, that means, best documentation, best community, best software for development, best software.
2 – Multi-Platform! Runs on Windows, Linux, Mac, and others. ( Mono ).
3 – If you want to make apps, make them. If you prefer games, make them too, with XNA!!.
So basically. I’ve been digging the msdn library and learning the language, and Windows Forms. I’m getting pretty good now. This will help me make better games with XNA too, so, its win win…
I highly recommend.
