wrap the call to the web service's EndXxxx() method in a try catch, and catch for a soap exception.  The exception wont be returned until you actually call the End method.  Also, if you dont call the End method, you'll never know that an exception occurred

    I have a delegate which I call BeginInvoke on. I use the waithandle.WaitOne
    to wait for the delegate to finish.
    If there is an exception in the delegate call, waithandle.WaitOne returns
    true and the asyncresult.IsFinished(Completed) also returns true.
    How do I know if there is an exception and the call was completed but with
    an exception?

Use Exception handling with try and catch block if a exception arisees in the try block when u use the delegates or function pointers is catched in catch block
