title: StreamSocket DataReader ReadToEnd extension method
body: <p>I would like to implement an extension method called ReadToEnd on the <code>Windows.Storage.Streams.DataReader</code> class. This should basically read all available data on the stream like System.IO.StreamReader.</p>
  
  <p>Trying to make porting of my non-compliant WinRT code as easy as possible.</p>
  
  <p>I'm not sure about how to achieve this, or if it is even possible.</p>
