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
  
  • If you are using SCiTE and your path enviroment variables for csc are setup correctlty you can just press
    • F7 to compile
      
    • F5 to run
      
• use mono to run the HelloWorld.exe created by mcs
  

  mono HelloWorld.exe
