  public class WaitHandle
  {
    static AutoResetEvent threadDone =
             new AutoResetEvent(false);
    public static void StartHere()
    {
      Console.WriteLine("Starting thread");
      Thread.Sleep(1000);
      threadDone.Set();
      Console.WriteLine("Finishing thread");
    }

    public static void Main()
    {
      Console.WriteLine("Starting Main");
      Thread t = new Thread(
                   new ThreadStart(StartHere));
      t.Start();
      threadDone.WaitOne();
      threadDone.Close();
      Console.WriteLine("Finishing Main");
