Question 1

How to implement automatic validation in Catel?

Accepted Answer

Inherit from ValidatableModelBase for models and override the ValidateFields method. For view models, use ViewModelBase with [ViewModelToModel] attributes to automatically map and validate properties from the model, as demonstrated in the README example code.

Question 2

Catel vs Prism for WPF development?

Accepted Answer

Catel excels with built-in features like context-aware view resolution and comprehensive utilities, while Prism is more modular with a larger ecosystem. Choose Catel for all-in-one MVVM solutions; Prism for flexibility and extensive community extensions.

Question 3

How to use Catel with Xamarin.Forms?

Accepted Answer

Include the Catel.MVVM library in your Xamarin.Forms project and leverage services like NavigationService. The framework is designed to work seamlessly with Xamarin, providing consistent MVVM patterns across mobile platforms.

Question 4

Does Catel support .NET 5 or .NET 6?

Accepted Answer

Catel mentions .NET Core cross-platform development in the build prerequisites, but you should verify compatibility in the official documentation, as support for newer .NET versions might not be immediately available or well-documented.

Question 5

How to set up dependency injection in Catel?

Accepted Answer

Use the ServiceLocator or TypeFactory from Catel.Core. Register types with ServiceLocator.Default.RegisterType and resolve them in view models or other classes, integrating smoothly with the MVVM framework for clean architecture.

Question 6

Is Catel good for small projects?

Accepted Answer

Catel is tailored for Line of Business applications and can be overkill for small projects due to its extensive features. Consider lighter alternatives unless you specifically need its advanced MVVM capabilities or professional support.
