ShareLinkTask instansiate a new page?

Question

In my browser app, I noticed when ShareLinkTask is called, the app's MainPage() is called again. How do I make sure the app does not navigate to the new instance of the MainPage when returning from ShareLinkTask ?

The reason I want the original page is that the app has to remember the LayoutRoot grid on that page in order to display an UI animation. But since the new LayoutRoot grid is a different instance, the animation is not running once the app return from ShareLinkTask .

What am I missing?

ShareLinkTask is one of the Launchers. Your application will be Deactivated when you use a Launcher and go into Dormant or Tombstoned mode. In the first case the MainPage constructor would not be called again after returning from Launcher, only the OnNavigatedTo method. To prepare for the second case, save the state of the animation in OnNavigatedFrom and read the saved state in OnNavigatedTo.
