How do I wait for a C# event to be raised?

Question

I have a Sender class that sends a Message on a IChannel:

public class MessageEventArgs : EventArgs {
  public Message

Useful sample with AutoResetEvent:

    using System;
    using System.Threading;

    class WaitOne
    {
        static AutoResetEvent autoEvent = new AutoResetEvent(false);

        static void Main()
        {
            Console.WriteLine("Main starting.");

            ThreadPool.QueueUserWorkItem(
                new WaitCallback(WorkMethod), autoEvent);

            // Wait for work method to signal.
            autoEvent.WaitOne();
            Console.WriteLine("Work method signaled.\nMain ending.");
        }

        static void WorkMethod(object stateInfo) 
        {
            Console.WriteLine("Work starting.");

            // Simulate time spent working.
            Thread.Sleep(new Random().Next(100, 2000));

            // Signal that work is finished.
            Console.WriteLine("Work ending.");
            ((AutoResetEvent)stateInfo).Set();
        }
    }
