I have a visualization layer bound to an observable collection of MapShapeData. There is a LineData in it whose initial points are Location.Empty. As I change Point1 and Point2, the line is correctly updated on the map. When I change Point1 and Point2 back to Location.Empty, the line stays on the map. I am expecting it to disappear.
This was the only simliar thread I saw:
