            AddHandler watcher.PositionChanged, AddressOf watcher_PositionChanged
            watcher.Start()

        End Sub

        Private Sub watcher_PositionChanged(ByVal sender As Object, ByVal e As GeoPositionChangedEventArgs(Of GeoCoordinate))
            PrintPosition(e.Position.Location.Latitude, e.Position.Location.Longitude)
            ' Uncomment the following to stop receiving updates after the first one.
            ' watcher.Stop()
        End Sub

        Private Sub PrintPosition(ByVal Latitude As Double, ByVal Longitude As Double)
