Hey,

I currently have an asynchronous call with a callback, which fires this method on completion:

private void TestConnectionToServerCallback(IAsyncResult iar)
{
    bool result;

    try
    {
        result = testConnectionDelegate.EndInvoke(iar);

        Console.WriteLine("Connection made!");
    }
    catch (EndpointNotFoundException e)
    {
        Console.WriteLine("Server Timeout. Are you connected?");
        result = false;
    }

    ...
}

With the EndpointNotFoundException firing when the server is down or no connection can be made. My question is this, if I want to recall the testConnectionDelegate with some kind of re-try button, must I first call testConnectionDelegate.EndInvoke where the exception is caught?

When I do call end invoke in the catch, I get another exception on result = testConnectionDelegate.EndInvoke(iar); whenever I call this method for the second time. This is "CommunicationObjectFaultedException". I'm assuming this is because I didn't end it properly, which is what I think I have to do.

Any help would be appreciated. Thanks - James
