I'm having trouble running the following code under the debugger (although it works correctly when it runs normally). The code calls a simple "Hello World" web service asynchronously and prints "Hello World" to the screen. My problem is that when I run it under the debugger the HelloWorldCallback method never fires. Can anyone tell me why?

Bill

using System;

namespace WebServiceDebugTest
{
    /// <summary>
    /// Summary description for Class1.
    /// </summary>
    class Class1
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main(string[] args)
        {

            localhost.Service1 webService = new WebServiceDebugTest.localhost.Service1();

            IAsyncResult ar = webService.BeginHelloWorld(new AsyncCallback(HelloWorldCallback),webService);

            Console.WriteLine("Push any key to quit ...\n");
            Console.ReadLine();

        }

        private static void HelloWorldCallback(IAsyncResult ar)
        {
            localhost.Service1 webService = ar.AsyncState as localhost.Service1;
            string result = webService.EndHelloWorld(ar);
Console.WriteLine("{0}\n",result);
        }
    }
}

The problem is that you are blocking the main STA Thread without pumping
messages. Remove the '[STAThread]' attribute, or pump messages, and you
should be good.
