title: Open Web Browser from XAML app
body: <p>I would like to open the external webbrowser from my XAML app, similar to this: <a href="https://stackoverflow.com/questions/4779363/want-to-open-link-in-external-browser-of-wp7">want to open Link in external browser of WP7</a></p>
  
  <p>I can't seem to find the WebBrowserTask object:</p>
  
  <pre><code>Dim wbt As New WebBrowserTask()
  wbt.Uri = New Uri("http://xxx.xxx.com/xxx.aspx")
  wbt.Show()
  </code></pre>
  
  <p>Is there another way for WindowsRT/XAML?</p>
  
  <p>Thanx!</p>
