Remarks
Use this property to connect a Page 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.
You can add a Window as the root visual, but only as a top-level window (with WS_OVERLAPPED), not as a child window.
