Windows Phone 7: GPS emulator

In your Windows Phone device you have a built-in Assisted GPS (aGPS), which can be used to access location informations by using the System.Device.Location namespace. The GeoCoordinateWatcher class supplies location data based on latitude and longitude coordinates. This is nice, but if you want to develop such an application it is necessary to emulate the GPS sensor.

In this Windows Phone Team Blog a very good article can be found to achieve this goal.
