title: Modeless dialog box in App store
body: <p>In C#, how can I show modeless dialog box  for a App store application?</p>
  
  <p>My app has multiple views and a long time task. I would like to show the task progress in a modeless box at the top-right corner of the screen.</p>
  
  <p>It is a information box, no interaction with the user and it should not affect to the user. The user must be able to navigate across the views, enter data, etc.</p>
