title: Silverlight 4 RC File Upload with Upload Progress: how to?
body: <p>It's been stated that one of the new features of Silverlight 4 RC is that it now supports upload progress.</p>
  
  <p>I'm assuming this means it's possible to make an upload file progress bar without "chunking" but I can't figure out how to do this, so how do we do this? Source code examples would be great.</p>
  
  <p>Thanks!</p>
