Title Body

in a Silverlight-Windows Phone 7-project I am creating an HttpWebRequest, get the RequestStream, write something into the Stream and try to get the response, but I always get a NotSupportedException: "System.Net.Browser.OHWRAsyncResult.AsyncWaitHandle threw an exception of type 'System.NotSupportedException' My production code is far more complicated, but I can narrow it down to this small piece of code: public class HttpUploadHelper { private HttpWebRequest request; private RequestState state = new RequestState(); public HttpUploadHelper(string url) { this.request = WebRequest.Create(url) as HttpWebRequest; state.Request = request; } public void Execute() { request.Method = "POST"; this.request.BeginGetRequestStream( new AsyncCallback(BeginRequest), state); } private void BeginRequest(IAsyncResult ar) { Stream stream = state.Request.EndGetRequestStream(ar); state.Request.BeginGetResponse( new AsyncCallback(BeginResponse), state); } private void BeginResponse(IAsyncResult ar) { // BOOM: NotSupportedException was unhandled; // {System.Net.Browser.OHWRAsyncResult} // AsyncWaitHandle = 'ar.AsyncWaitHandle' threw an // exception of type 'System.NotSupportedException' HttpWebResponse response = state.Request.EndGetResponse(ar) as HttpWebResponse; Debug.WriteLine(response.StatusCode); } } public class RequestState { public WebRequest Request; } } Does anybody know what is wrong with this code?
