If you developing for Windows Phone 8 you better use Tasks.

For example

HttpWebRequest req = WebRequest.CreateHttp(url);
req.Method = "GET"; //get is default

var tsk = Task.Factory.FromAsync<WebResponse>(req.BeginGetResponse, req.EndGetResponse, req);

if (!tsk.Wait(60000))
                        {
                            throw new Exception("Timeout");
                        }

HttpWebResponse resp = tsk.Result as HttpWebResponse;

string body = "";

using (StreamReader reader = new StreamReader(resp.GetResponseStream()))
{
   body = reader.ReadToEnd();
}

I would think that using WebClient would be a good option.

What exactly are you passing? Are you passing the parameters correctly?
I agree with TechGeek.. Use WebClient.

Can you open url in IE in emulator? May be you just have a problem with connection?

Hi,
Here is my answer.

      WebClient webClient = new WebClient();
      webClient.DownloadStringAsync(new Uri(requestUrl));
      webClient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(Detail_DownloadStringCompleted); 


       private void Detail_DownloadStringCompleted(object sender , DownloadStringCompletedEventArgs e) { 
            string responseTxt =  e.Result.ToString().Trim();
        }
