I don't take my laptop with me very often, but the Pocket PC is always there with me. Sometimes I feel like doing something productive on it, and I'm pretty sure I heard there are development environments for the Pocket PC.
Is there such thing for compiling .NET code; especially C#?

There's Pocket C#: http://www.only4gurus.com/v3/preview.asp?ID=5984
I'm not sure how good that is.

I can already see: The first PocketPC application developed entirely on a PocketPC, with a stylus!

For C++ there's also Pocket GCC: http://sourceforge.net/projects/pocketgcc
