    I suspect this may be because you are performing a BeginGetRequestStream on a request object for which you have specified the “GET” method.

    When performing a “GET” the server will not be expecting an entity body in the request hence you should proceed straight to BeginGetResponse. Also specifying a ContentType on the request is not necessary, it specifies the type of content being sent in the entity body of the request but as stated a “GET” doesn’t send any content it only gets content.
