Again, not entirely sure what it is you are going for, but my interpretation:

If you want to ensure that only a single instance of your process is ever running at once, insert the following code at the beginning of your main method (in Program.cs).

if (Process.GetProcessesByName (Process.GetCurrentProcess().ProcessName).Length > 1)
{

    //instance of the process already active, exit
    return;

}

You will need to include using System.Diagnostics at the top of your file.

Note that this is not a perfect solution, in that if a user starts two instances of the process at exactly the same time, then they will both probably close.
