title: WP8 - WebBrowser class : How to handle downloading of file?
body: <p>I have created a simple app in WP8 to display web pages using the Microsoft.Phone.Controls.WebBrowser class.
  I am able to load the page, navigate links, move back and forward in history.
  Apart from this basic functionality I also want to provide means to download files which cannot be displayed within the browser like say .ppt or .mp3.</p>
  
  <p>I have not been able to find anything in the WebBrowser class documentation to initiate a download. There is just a Navigate function which takes a URL to load.</p>
  
  <p>So can a download be done using WebBrowser class?</p>
