async private void txtLocation_Click(object sender, RoutedEventArgs e)
{
    Geolocator geo = new Geolocator();
    Geoposition position = await geo.GetGeopositionAsync();
    txtLocation.Text = "Latitude: " + position.Coordinate.Point.Position.Latitude.ToString() + 
               " Longitude: " + position.Coordinate.Point.Position.Longitude;
}

Just create an instance of the Geolocator class and invoke the GetGeopositionAsync method . This will return the Geoposition which contains the Coordinates from which the latitude and longitude can be detected.
