Create your own operating system!

Step 2 Creating the project

After downloading the file CosmosUserKit.MS4, run it and follow the setup instructions. Visual studio will warn you about unsigned code and potential danger and blah blah blah. Cosmos doesn't have any of that, so just click OK.

Now, if you open up Visual C#, and under the heading Recent projects, you will see the text "Create...project". Click this. It will be where we write all the code for the OS. Name it whatever you please. Now, you will see an option under My templates labeled CosmosBoot. Double click it to open up the Cosmos template, and then double click the "program.cs" text over on the right. You should see this text:

using System;
using Cosmos.Compiler.Builder;

namespace CosmosBoot1
{
    class Program
    {
        #region Cosmos Builder logic
        // Most users wont touch this. This will call the Cosmos Build tool
        [STAThread]
        static void Main(string[] args)
        {
            BuildUI.Run();
        }
        #endregion

        // Main entry point of the kernel
        public static void Init()
        {
            var xBoot = new Cosmos.Sys.Boot();
            xBoot.Execute();
            //There's supposed to be a bit of text here. Change it to Console.WriteLine("Hello world!");
        }
    }
}

In the next step we'll boot up our (very) basic OS.
