Current behavior

Instance methods calls like _canvas.GetDispatcherCompat().Schedule(_canvas.InvalidateMeasure)
causes a cast exception on Windows:

InvalidCastException: 'Specified cast is not valid.'

Affected platform(s): Windows (WinUI)

Should be made with lambda expression:

_canvas.GetDispatcherCompat().Schedule(()=> _canvas.InvalidateMeasure())
owner.GetDispatcherCompat().Schedule(()=> owner.InvalidateMeasure())
