C# HOW TO - HELLO WORLD application

This program, only prints out "Hello World!" to the default output. For C# with a Windows machine, this is the Command Promt.
To get Started:


**********************************************************************

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1 // THE NAMESPACE, NOT THAT IMPORTANT AT THIS TIME LIVE IT AS IS
{
    class Program // CLASS NAME THIS NAME REPRESENTS THE "Program" Object
    {
        static void Main(string[] args) //THIS IS WHERE THE EXECUTION BEGINS
        {
            Console.WriteLine("Hello World!"); //PRINTS THE LINE IN THE CONSOLE
            Console.ReadKey(); //BLOCKS UNTIL YOU PRESS A KEY (FOR DISPLAY PURPOSES)
        }
    }
}

**********************************************************************

• Open Visual C# Express or Microsoft Visual Studio 2008 or 2010 or whatever version you like.

• Go to File > New Project > Console Application. (check the bottom for screenshots on how to do this)

• The Only two lines I added were:

1. Console.WriteLine("Hello World!"); 
2. Console.ReadKey(); 

• The green text is used for giving additional info on why you put a specific line of code, they are called comments. You can write whatever your want after the // as it will be considered as short comments.
  For a multiline comment you can use or //
                                                             //
  or group your comment like this /* your comment here */

Now Press the Start Debugging button to compile and run the application.



File > New Project.

  

Now choose Console Application.

 

Final Code, generated by Visual C# Express plus the two lines I added.
