我有一个 Windows Phone 8 应用程序，我将一个对象序列化为 JSON 并创建一个HTTPWebRequest对象并尝试 POST 到 WCF 服务。我面临的问题是我得到一个：The remote server returned an error: NotFound。

这是 WP8 中的代码：

var jsonData = JsonConvert.SerializeObject(ReportSightingRequest.Instance);
var uri = new Uri("URLGoesHere");
var webRequest = (HttpWebRequest)WebRequest.Create(uri);
webRequest.Method = "POST";
webRequest.ContentType = "application/json";
webRequest.ContentLength = jsonData.Length;
webRequest.BeginGetRequestStream(ar =>
{
    try
    {
        using (var os = webRequest.EndGetRequestStream(ar))
        {
            var postData = Encoding.UTF8.GetBytes(jsonData);
            os.Write(postData, 0, postData.Length);
        }
    }
    catch (Exception ex)
    {
        Debug.WriteLine(ex);
    }

    webRequest.BeginGetResponse(
        ar2 =>
        {
            try
            {
                using (var response = webRequest.EndGetResponse(ar2))
                using (var reader = new StreamReader(response.GetResponseStream()))
                {
                    var received = reader.ReadToEnd();
                }
            }
            catch (Exception ex)
            {
                Debug.WriteLine(ex);
            }
        }, null);
}, null);

这是在“输出”窗口中吐出的内容：

An exception of type 'System.Net.WebException' occurred in System.Windows.ni.dll and wasn't handled before a managed/native boundary
A first chance exception of type 'System.Net.WebException' occurred in System.Windows.ni.dll

   at System.Net.Browser.ClientHttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
   at [Namespace].<>c__DisplayClass2.<ReportSighting>b__1(IAsyncResult ar2)

WCF 服务工作正常，因为有其他设备使用它。使用提琴手调用请求也可以，控制台应用程序成功没有问题。

任何人都可以看到我要去哪里可怕的错误？
