Notes to Inheritors
In Win32, a window is expected to be the size requested by layout at the time the window is created. Derived classes should override this method only if they have additional information regarding required window size.
The specific implementation here is already an override of the FrameworkElement virtual member, which bases size constraints on the window handle and treats a zero value in one or more dimensions as a non-constraint. The WindowsFormsHost class also overrides a MeasureOverride(Size) implementation that will result in a clip of the form if it is too large.
