To implement StyledProperty and DirectProperty in Avalonia, declare them within your custom control class using the appropriate registration methods. StyledProperty supports styling and animation, while DirectProperty wraps existing CLR properties for lightweight data binding.

StyledProperty supports styling, animation, and inheritance in Avalonia controls. DirectProperty wraps existing CLR properties for efficiency, while AttachedProperty allows parent controls to attach property values to child elements, commonly used for layout configuration.

Observe Avalonia property changes by overriding OnPropertyChanged to handle static change callbacks, or use GetObservable to subscribe to reactive property value streams. Both methods drive reactive UI updates when property values transition.

Avalonia property inheritance propagates values down the visual tree, metadata overrides customize default behaviors in derived controls, and value coercion intercepts property assignments to enforce constraints and manage value priority.

Yes, you can define a StyledProperty on a parent control for styling and animation, then use an AttachedProperty to configure child layout behavior. This combination allows complex UI component architecture across control hierarchies.
