title: Windows Phone 8.1 MapIcon Click event
body: <p>I'm writing a Windows Phone 8.1 app(Windows Runtime version), and I used the MapIcon class to place the icons on the map control. However, I hope these icons can react to the "click" event so that I could show more details after a user has clicked a specific icon. I googled and wasn't able to find an answer. Is it possible, or do I have to create my own class in order to achieve this goal(and how)? </p>
  
  <p>It's my first time to develop the Windows Phone 8.1 app, so any suggestions are really appreciated. Thank you.</p>
