title: DataContractJsonSerializer on Windows Phone 7
body: <p>I'm trying to serialize an object into JSON in Silverlight on Windows Phone 7. My problem is, and this sounds stupid: I can't find it. According to <a href="http://msdn.microsoft.com/en-us/library/system.runtime.serialization.json.datacontractjsonserializer%28VS.95%29.aspx">MSDN</a>, it should work and be available on WP7.</p>
  
  <p>Can somebody help me? This is stopping me at this point. I haven't been able to get beyond this :(</p>
