ex = {"Either ContentLength must be set to a non-negative number, or SendChunked set to true in order to perform the write operation when AllowWriteStreamBuffering is disabled."}
This was a bit confusing since I didn't get this error when running from a windows client. I finally figured out that I have to allow writing to the stream:
private void SendData(WebRequest request, object dto)
{
// I had to add this for the CF framework. It isn't true by default.
if (request is HttpWebRequest)
((HttpWebRequest) request).AllowWriteStreamBuffering = true;
using (Stream requestStream = request.GetRequestStream())
{
if (IsJsonRequest(request))
SendDataAsJson(requestStream, dto);
else SendDataAsXml(requestStream, dto);
}
}
