Your GUI won't be blocked any more if you call the webserver async. Use this code to try: (instead of request.GetResponse)

        request.BeginGetResponse((ar) =>
        {
            var response = (HttpWebResponse)request.EndGetResponse(ar);
            responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

            // do something with the string
        }, null);
