Property Value

The root visual object of the window.

Use this property to connect a Page or Window (or another root visual) to the HwndSource.

Scale transformations should not be applied to the RootVisual of an HwndSource, because this can disable SizeToContent behavior. The content will scale, but the enclosing window will not. Instead of applying the transformation to the object that is the RootVisual, apply the transformation to an object that is a child element of the RootVisual. You might need to add an extra enclosing element to the WPF content such as a panel in order to provide a scaleable object.
