This method has no default implementation. A typical WPF framework-level element uses the override implementation from FrameworkElement. The FrameworkElement implementation invalidates the Width and Height properties and handles the basics of remaking the layout. Overriding at the UIElement level implies that your element implementation is deliberately not using the WPF framework-level implementation, and therefore your element must handle layout logic more directly, typically by writing a replacement layout system.
