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.

Important Note:
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.

To use the Maps task

1. Add a reference to the System.Device assembly to your project.

2. Add the following statements to your code.

   Imports Microsoft.Phone.Tasks
   

   using Microsoft.Phone.Tasks;
   

   Imports System.Device.Location
   

   using System.Device.Location;
   

3. Add the following code to your application wherever you need it, such as in a button click event. To test this procedure, you can put the code in the page constructor. This is the code to launch the task.

           Dim mapsTask As MapsTask = New MapsTask()
   
           'Omit the Center property to use the user's current ___location.
           'mapsTask.Center = new GeoCoordinate(47.6204, -122.3493);
   
           mapsTask.SearchTerm = "coffee"
           mapsTask.ZoomLevel = 2
   
           mapsTask.Show()
   
   

               MapsTask mapsTask = new MapsTask();
   
               //Omit the Center property to use the user's current ___location.
               //mapsTask.Center = new GeoCoordinate(47.6204, -122.3493);
   
               mapsTask.SearchTerm = "coffee";
               mapsTask.ZoomLevel = 2;
   
               mapsTask.Show();
