Remarks

Launch the Contacts application by calling Show()()(). Obtain the result of the chooser operation by handling the Completed event.

Important Note:
On Windows Phone, your application may be deactivated while the Contacts application is in the foreground. To ensure that your application receives the result of the AddressChooserTask, the object must be declared with class scope within the PhoneApplicationPage class and you must call the chooser constructor and assign the Completed event delegate within the page’s constructor. For more information about how to handle the activation and deactivation of your application, seeApp activation and deactivation for Windows Phone 8.
