After upgrading to MS 10 the EditInteractiveOverlay is not working as it previously did. There is now a new layer, SelectedControlPointLayer which contains the point being moved when editing vertices. But the real problem is that when a feature is added to EditInteractiveOverlay.EditShapesLayer the control points do not draw correctly. Only one control point is visible.
I have attached a sample project to make it easy for you to see.
