Do not attempt to set this property, either in XAML or in code, if using the WPF framework-level layout system. Nearly all typical application scenarios will use this layout system. The layout system will not respect sizes set in the property directly. The property is declared writable only to enable certain WPF core-level bridging cases that deliberately circumvent the typical layout protocols, such as support for the Adorner class.
