==========================================
(ref: http://www.mono-project.com)

- Add the following to /etc/apt/sources.list
 deb http://badgerports.org lucid man

$ sudo apt-get install gtk-sharp2
$ sudo apt-get install mono-xsp2

Having installed the above, create a sample program HelloWorld.cs with following content:
using System;

public class HelloWorld
{
  static public void Main ()
  {
    Console.WriteLine ("Hello Mono World!");
  }
}

Compile the HelloWorld.cs program using:
$ gmcs HelloWorld.cs

(This should result in HelloWorld.exe)

Run the program:
./HelloWorld.exe 

output:
Hello Mono World!
