Occurs when a Chooser task is completed.
Assembly: Microsoft.Phone (in Microsoft.Phone.dll)
XMLNS for XAML: Not mapped to an xmlns.
To ensure that your application receives the result of the Chooser task when your application is reactivated, the Chooser object must be declared with a global scope within the T:Microsoft.Phone.Controls.PhoneApplicationPage class and you must initialize the Chooser and assign the E:Microsoft.Phone.Tasks.ChooserBase`1.Completed event delegate in the T:Microsoft.Phone.Controls.PhoneApplicationPage constructor. For more information about how to handle the activation and deactivation of your application, see The Windows Phone Task Model.
