This is the only FrameworkElement that overrides and then seals.

@tonyhallett Can you please elaborate on what problem are you facing in your application?

tonyhallett commented 2 years ago

I wanted my derivation to use OnPropertyChanged. I wanted to provide a generic solution across multiple controls and overriding metadata in a static constructor is not an option.

For my use case I have been able to use multi binding.
