How to use the Maps task for Windows Phone 8
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
The Maps task launches the Maps application. You can provide a search string that is used to find and mark locations on the map. You can optionally specify a center point for the map that appears. If you do not specify the center, the user’s current location is used as the center. You can also specify the zoom level to use initially when the map appears.
By using Launchers, you help provide a consistent user experience throughout the Windows Phone platform. For more information, see Launchers and Choosers for Windows Phone 8.
The Maps application will not be launched if the device is in a location where it is not supported. Instead, a dialog will be displayed to the user indicating that Maps is unavailable in their location.
