title: Where is the "WebClient.UploadString" Method in Windows Phone 7?
body: <p>I have some old code that I'm converting to use in Windows Phone. The old code was : </p>
  
  <p>private String Post(string url, string Data)
  {
  return webClient.UploadString(url, "POST", Data);
  }</p>
  
  <p>The problem is there isn't a function called UploadString in webClient. Instead, it's the asynchronous one (UploadStringAsync). How can I convert the above old code to immediately return a string response as UploadString used to do ? </p>
