Silverlight 4.0 - HttpWebRequest throwing ProtocolViolationException

Question

I get a "System.Net.ProtocolViolationException: operation is not valid due to the current state of the object." when trying to call

 var request = (HttpWebRequest)WebRequest.Create(uri);

 request.Method = "GET";

 request.ContentType = "text/xml";

 request.BeginGetRequestStream(RequestCompleted, request);

Answer 1

I suspect that this may be due to what you are executing BeginGetRequestStreamin the request object for which you specified the GET method.

"GET" , BeginGetResponse. , ContentType , , , , , "GET" , .
