  class Program
   {
     static void Main(string[] args)
      {
        Console.WriteLine("This is my First C# Program");
      }
   }
}

Step 2: Now save this program as Chapter1.cs. You must choose All Files in save as type box.

Step 3: Go to Start > All Programs > Microsoft Visual Studio 2005 or 2008 > Visual Studio Tools > Visual Studio 2005 or 2008 Command Prompt.
