HttpWebRequest Timeout in WP7 not working with timer

Question

Since WP7 HttpWebRequest does not support timeout, I\'m using a timer to implement the functionality. Below is an example. I call GetConnection() from a UI form. But ReadCal

Your code works as expected for me. When you call Abort() on a pending request, your ReadCallback is expected to fire. Then when you call EndGetResponse() you should get a WebException with Status=RequestCanceled.

Try this slightly modified code to see this in action:

private void ReadCallback(IAsyncResult asynchronousResult)
{
    _stopTimer = true;
    HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;

    try
    {
        var m_response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);
        System.Diagnostics.Debug.WriteLine("Success");
    }
    catch (WebException exc)
    {
        System.Diagnostics.Debug.WriteLine(exc.Status);
    }
}

"The Abort method cancels a request to a resource. After a request is canceled, calling the BeginGetResponse, EndGetResponse, BeginGetRequestStream, or EndGetRequestStream method causes a WebException with the Status property set to RequestCanceled."
