        {
            GeoCoordinateWatcher watcher;
            watcher = new GeoCoordinateWatcher();

            watcher.PositionChanged += (sender, e) =>
            {
                var coordinate = e.Position.Location;
                Console.WriteLine("Lat: {0}, Long: {1}", coordinate.Latitude,
                    coordinate.Longitude);
                // Uncomment to get only one event. 
                // watcher.Stop(); 
            };
