Cosmos "Hello world" Plug generate error

I've just installed Cosmos and tried to run the test program given by default. That's the code:

using System;
using System.Collections.Generic;
using System.Text;
using Sys = Cosmos.System;

namespace CosmosKernel2
{
    public class Kernel : Sys.Kernel
    {
        protected override void BeforeRun()
        {
            Console.WriteLine("Cosmos booted successfully. Type a line of text to get it echoed back.");
        }

        protected override void Run()
        {
            Console.Write("Input: ");
            var input = Console.ReadLine();
            Console.Write("Text typed: ");
            Console.WriteLine(input);
        }
    }
}

When I try to compile it, it says: 

Error   8   Plug needed. System.Void  System.Threading.Monitor.Exit(System.Object)
   at Cosmos.IL2CPU.ILScanner.ScanMethod(MethodBase aMethod, Boolean aIsPlug) in c:\Data\Sources\Cosmos\source2\IL2CPU\Cosmos.IL2CPU\ILScanner.cs:line 663

I'm using Visual Studio 2010, I have installed all requirements listed here: http://cosmos.codeplex.com/releases/view/123476

Thank you in advance!

It seems that Cosmos isn't working well with windows 8/8.1. So the only solution is to either install Windows 7 or run a virtual machine with installed Windows 7 (the latter worked for me)

"plug needed" error means that you have used some method which relies on an internal call or PInvoke, and thus Cosmos cannot compile it.

You probably use a method that has not been plugged yet or maybe missing a reference to that implementation (which makes Cosmos think it is not implemented)

Use the below guides to help you getting started:

Update: Try using something similar to this code:

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!");
        }
    }
}
