Read XML from Azure CDN Marshalled error

Question

I would like to load an XML file stored in Azure CDN in a Windows 8.1 App. This code throws Marshaling error:The application called an interface that was marshalled for a different thread. (Exception from HRESULT:
0x8001010E (RPC_E_WRONG_THREAD))
       public async Task<XDocument> LoadXmlFromCDNAsync()
  var url = new Uri("http://azXXXXXX.vo.msecnd.net/cdn/Data.xml");
            var handler = new HttpClientHandler() { AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip };
            var client = new HttpClient(handler);
            XDocument doc = new XDocument();
            using (var stream = await client.GetStreamAsync(url))
                doc = XDocument.Load(stream);
            return doc;
Thanks.

Hi,
I test your codes. And the result below:
I can successfully load the XML file. I think there is no problem in the codes which you used to load an XML file.
And as the error says, the problem is the thread on which the call occurs: the app cannot manipulate UI elements from non-UI threads.  That error usually means you are calling something that requires the UI thread from a different thread. You can
call Dispatcher.RunAsync to marshall a task back to the UI thread.
