The term 'overlay' in the ArcGIS Runtime .NET SDK may be new to some developers. In other Esri SDK's the concept of an overlay is often termed a 'MapTip'. A MapTip is a user-assistance component that displays an on-screen description of a map feature when the mouse is paused over or a users taps on a feature.

In order to maintain good performance in your application it is recommended to not place too many or overly complex UIElement objects within the UIElementCollection. These graphical UIElement objects are drawn via software rendering of the Operating System and performance can vary across devices. Keeping UIElements to a minimum, say under 20, should not impact the performance of your application when setting the MapView.Overlays Property.
