Try this example: using System; using System.Threading; class Program { static void Main() { // create Mutex with a 'unique' name Mutex m = new Mutex(false Raps Gao Single Instance App); // give any existing instance a chance to shutdown if (!m.WaitOne(TimeSpan.FromSeconds(2) false)) { Console.WriteLine(There is already an existing instance running); } else { Run(); } m.Dispose(); } static void Run() { Console.WriteLine(Program is running - please any key to close down); Console.ReadKey(true); } }
