Mono is a cross-platform Free Software .NET compiler and runtime.

Programming in C# is required for ECE 4564 Network Application Design. Thanks to Mono, all assignments for that class can be completed from Linux, if GTK# is substituted for Windows Forms.

[edit] Development Environment

The recommended development environment is MonoDevelop, which as of version 2.0 comes bundled with a GUI designer. Note that the debugger and API documentation are packaged separately. To install everything on Ubuntu Karmic, run:

$ sudo apt-get install mono-complete monodevelop monodevelop-debugger-mdb monodoc-browser
