CSharp on RPi
C# can be used, in both compiled and interactive mode, on the Raspberry Pi via Mono.
To use C#, you must first install the mono-complete package. Under Debian:
sudo apt-get install mono-complete
sudo pacman -S mono-complete
To use the interactive C# environment, simply type "csharp" at a command prompt. Type some C# code, and it will be executed or evaluated immediately. Press Ctrl+D to exit.
