What problem does it solve?

Working with Avalonia's property system can be verbose and error-prone, especially when employing StyledProperty, DirectProperty, and AttachedProperty across complex controls and hierarchies.

Core Features & Use Cases

• Property types: StyledProperty, DirectProperty, and AttachedProperty with practical examples for common controls.
• Property lifecycle: Inheritance, metadata overrides, coercion, and value priority handling.
• Observability: Reacting to OnPropertyChanged and GetObservable to drive reactive UI updates.
• Use Case: Build a custom control that combines StyledProperty styling/animation with a supporting AttachedProperty for child layout configuration.

Quick Start

Create a simple control that defines a StyledProperty, a DirectProperty, and an AttachedProperty and demonstrate inheritance and coercion.
