Location-aware APIs

Learn about the APIs that can be used for developing location-aware apps in Windows 8.

Building location-aware Windows Store apps

Windows Store apps can use the Windows Runtime geolocation API, in the Windows.Devices.Geolocation namespace. Windows Store apps can be built in Javascript, C#, C++, or Visual Basic.
