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

            // Begin listening for location updates.

Comentarios

La longitud puede oscilar entre -180,0 y 180,0. La longitud se mide en grados este o oeste del meridiano primo. Los valores negativos son oeste del meridiano primo y los valores positivos son este del meridiano primo.
