Remarks

ElementCompositionPreview allows access to the Windows.UI.Composition.Visual object backing a XAML element with the GetElementVisual method. Once the backing object has been retrieved it can be manipulated using the Windows.UI.Composition namespace. This allows properties of the object to be changed, like the orientation, or additional objects to be added to the XAML composition tree.
