title: phone:webbrowser does not open PDF files (Windows Phone 8)
body: <p>I have build an app with a webbrowser in it. It's working fine but when I try to navigate to an adress like bla.<strong>pdf</strong> the webbrowser shows nothing.
  I solved this problem with automatically open the Internet Explorer if the adress is linking to a pdf file.</p>
  
  <p>Is there a better solution? I want to open that PDF file in my own app and I dont want to open the Internet Explorer everytime. Any suggestions?</p>
