Adorners are not implemented in UWP.
An Adorner is a common FrameworkElement associated with UIElement . Decoders are displayed in AdornerLayer , which is a rendering surface that always sits on top of a decorated item or collection of decorated items. The rendering of an adorner is independent of the rendering of the UIElement to which the adorner is bound. The lawyer is usually located relative to the element to which he is attached, using the standard two-dimensional origin, located in the upper left corner of the decorated element.
