This event is raised when the application is launched by the user. This include the user tapping the icon for your application from the installed programs list or by tapping the Tile for your application on the device’s Start screen. You should not load content from isolated storage or the web during this event handler because it will cause the application to load slowly. Also, the application should not imply that it is resuming from a previous session.
