Animate application icon in windows phone

I have tried googling for this and came up empty. What I want is a tutorial or example code of how to change my icon on the windows phone like the people application or SMS. For example when you get a new SMS message it puts a number next to the face in the icon. Is there any way for me to do that 开发者_StackOverflowin my app?

You need to send a Tile Push Notification.

This allows you to update the image, text and (optionally) a number.

Push notifications shoudl be triggered from a remote [web] service.

You can also have the tile update periodically using a ShellTileSchedule.

You can update your application's Tile using Push Notifications from a web service registered with a Microsoft Push Notification Service. However, this isn't absolutely necessary. You can even update your tiles without push notifications, by setting a ShellTileSchedule. The minimum update interval is 1 hour, however. See here.
