6# Avalonia ViewModels with Zafiro
7 
8This skill provides a set of best practices and patterns for creating ViewModels, Wizards, and managing navigation in Avalonia applications, leveraging the power of **ReactiveUI** and the **Zafiro** toolkit.
9 
10## Core Principles
11 
121.  **Functional-Reactive Approach**: Use ReactiveUI (`ReactiveObject`, `WhenAnyValue`, etc.) to handle state and logic.
132.  **Enhanced Commands**: Utilize `IEnhancedCommand` for better command management, including progress reporting and name/text attributes.
143.  **Wizard Pattern**: Implement complex flows using `SlimWizard` and `WizardBuilder` for a declarative and maintainable approach.
154.  **Automatic Section Discovery**: Use the `[Section]` attribute to register and discover UI sections automatically.
165.  **Clean Composition**: map ViewModels to Views using `DataTypeViewLocator` and manage dependencies in the `CompositionRoot`.
