WP7 HttpWebRequestでエラーが発生しました

Question

私はHttpWebRequestのようなメソッドを呼び出していますので、このようなエラーが表示されます このようなコードです。

HttpWebRequest objHttpWebRequest = System.Net.WebRequest.CreateHttp("http://url"); 
     objHttpWebRequest.BeginGetResponse(r => 
     { 
      WebResponse response = null; 
      try 
      { 
       response = objHttpWebRequest.EndGetResponse(r); //End Async Call to the URL 
       using (var stream = response.GetResponseStream()) 
       using (var reader = new StreamReader(stream)) //get data in StreamReader 
       { 
        string contents = reader.ReadToEnd(); //read content from reader and store it in content 
        XElement xmlResult = XElement.Parse(contents); 
        AEGAPI.clsGlobal.RandomToken = xmlResult.Value; 
       }

WebClient.DownloadStringAsync（）を使用する方が簡単でしょうか？

void startDownload(Uri url) 
{ 
    WebClient wc = new WebClient(); 
    wc.DownloadStringCompleted += MyMethod; 
    wc.DownloadStringAsync(url); 
} 
void MyMethod(object sender, DownloadStringCompletedEventArgs e) 
{ 
    var contents = e.Result; 
    XElement xmlResult = XElement.Parse(contents); 
    AEGAPI.clsGlobal.RandomToken = xmlResult.Value; 
}
