  1. open a text editor (I like to use SCiTE)
  2. type in
//HelloWorld in c#

using System;
namespace HelloClass
    class HelloWorld
        public static void Main()
                Console.WriteLine("Hello World!");

3 Save the file as HelloWorld.cs
4 Coplile the .cs file using csc or mcs
5 Use csc (windows) or mcs (*nix) ro compile

  • csc run the HelloWorld.exe created by csc
  • use mono to run the HelloWorld.exe created by mcs
  mono HelloWorld.exe
