title: UWP Modal Window
body: <p>I want to show a modal window on the screen in my Universal Windows Platform app (C#), just like the standard Mail-app does when you add an account. Or when you're signing in to a service (like facebook) in an app.</p>
  
  <p><em>Windows mail app with modal window:</em>

  <p>You can move this window around, but it's not in the taskbar and it is modal.</p>
  
  <p>Does anyone know how to do this? It shouldn't be so hard but i can't find anything about it.</p>
