Dependency Properties
Dependency properties enable advanced property behaviors such as data binding, animation, and styling. However, implementing dependency properties in WPF often requires writing repetitive and error-prone boilerplate code, which can slow down development and introduce bugs.
Metalama.Patterns.Wpf
addresses this issue by allowing developers to generate dependency properties directly from C# automatic properties. This eliminates the need for boilerplate code, boosts productivity, and ensures cleaner, more maintainable code.
Metalama.Patterns.Wpf
is a production-ready, professionally supported, and open-source aspect library.
Available for WPF only.
Benefits
- Boost your productivity. Generate dependency properties from C# automatic properties without boilerplate code.
- Reduce human errors. Eliminate repetitive code that is prone to mistakes.
- Improve maintainability. Keep your codebase clean and easier to understand.
- Seamless integration. Works with existing WPF projects without requiring major refactoring.
- Customization. Easily add validation rules or
OnPropertyChanged
callbacks tailored to your needs.
Features
