Error de configuración Hay definida una sección ‘system.web.extensions/scripting/scriptResourceHandler’ duplicada

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(“https://www.bazm.mx/services/proxy.de”));
request.ContentType = “application/x-www-form-urlencoded”;
request.Method = “POST”;
request.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), request);

Y mis métodos siguientes son estos:

private static void GetRequestStreamCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;

Stream postStream = request.EndGetRequestStream(asynchronousResult);

XDocument document = XDocument.Load(“XMLFiles/XML.xml”);
string postData = document.ToString();

byte[] byteArray = Encoding.GetEncoding(“iso-8859-1″).GetBytes(postData);

postStream.Write(byteArray, 0, postData.Length);
postStream.Close();

request.BeginGetResponse(new AsyncCallback(GetResponseCallback), request);
}

private static void GetResponseCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;

HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);
Stream streamResponse = response.GetResponseStream();
StreamReader streamRead = new StreamReader(streamResponse);
string responseString = streamRead.ReadToEnd();
Console.WriteLine(responseString);

streamResponse.Close();
streamRead.Close();

response.Close();
}
