And here's an excerpt from the article:

 

 

Capabilities

The Location capabilities has to be set in the app manifest file for the app to work fine when using the location APIs.

If the Location capabilities are not set in manifest file, the following is the behaviour.

1. If the App is targeted at Windows Phone 7.1, then a status error will be received when trying to start the GeoCoordinate Watcher.

2. If the App is targeted at Windows Phone 8, then the app will throw UnauthorizedAccessException.

Setting the location capabilities is pretty easy, you will need to include the ID_CAP_LOCATION in the Capabilities section of your WMAppManifest.xml . Note that you should also be setting the ID_CAP_NETWORKING.

<``Capabilities``>

<``CapabilityName``=``"ID_CAP_LOCATION"/> < Capability Name="ID_CAP_NETWORKING"/>

...

</``Capabilities``>

If you are using Microsoft Visual Studio 2012, you can add the capabilities with the GUI editor as shown in the below screenshot.
