In this video tutorial I walk through the fundamentals of calling Web Services asynchronously from an ASP.NET page using the .NET 2.0 event driven model exposed by Web Service proxy objects. There are several different options for calling Web Services asynchronously including polling, callbacks and wait handles, but the event driven model is quite easy to use and doesn’t put as much pressure on the ASP.NET thread pool as the other options.

    When I create the WSProxies proxy object, I cannot access that object. i.e the line " WSProxies.Service proxy" gives me an error saying  WSProxies is an unknown type, any idea why this might be?

    Hi.
    Thanks for the video.

    The web service I want to call requires authentication via a referrer attribute. I can’t figure out how to “add web reference” and create a proxy.
    I’ve managed to call it via a HttpWebResponse but I’d like to do it asyncronously so I can call it roughly 100 times, passing a parameter each time.
    If I manage to get round the issue of creating the proxy class, would I need to have 100 event handlers?

    Thanks in advance of your kind response.
