Dll Injection в C#

Здравствуйте, хочу сделать Dll Injection в C#. Нашел код :

DLL in a process

        }  
    }  
}  

my DLL (class application):

Code:

using System;  
using System.Collections.Generic;  
using System.Text;  
using System.Windows.Forms;  
using System.Runtime.InteropServices;  
  
namespace L2Soul  
{  
    public class Class1  
    {  
        [DllImport("user32.dll")]  
  
        public static extern short GetAsyncKeyState(System.Windows.Forms.Keys vkey);  
  
        public void Main()  
        {  
            while (true)  
            {  
                if (Convert.ToInt32(GetAsyncKeyState(Keys.Z).ToString()) < 0)  
                    MessageBox.Show("OK");  
                else if (Convert.ToInt32(GetAsyncKeyState(Keys.X).ToString()) < 0)  
                {  
                    MessageBox.Show("GOING DOWN");  
                    break;  
                }  
            }  
        }  
    }  
}  

Должна запустится DLL. Но не запускается =(
