# Avalonia ViewModels with Zafiro This 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. ## Core Principles 1. **Functional-Reactive Approach**: Use ReactiveUI (`ReactiveObject`, `WhenAnyValue`, etc.) to handle state and logic. 2. **Enhanced Commands**: Utilize `IEnhancedCommand` for better command management, including progress reporting and name/text attributes. 3. **Wizard Pattern**: Implement complex flows using `SlimWizard` and `WizardBuilder` for a declarative and maintainable approach. 4. **Automatic Section Discovery**: Use the `[Section]` attribute to register and discover UI sections automatically. 5. **Clean Composition**: map ViewModels to Views using `DataTypeViewLocator` and manage dependencies in the `CompositionRoot`. ## Guides - ViewModels & Commands: Creating robust ViewModels and handling commands. - Wizards & Flows: Building multi-step wizards with `SlimWizard`. - Navigation & Sections: Managing navigation and section-based UIs. - Composition & Mapping: Best practices for View-ViewModel wiring and DI. ## Example Reference For real-world implementations, refer to the **Angor** project: - `CreateProjectFlowV2.cs`: Excellent example of complex Wizard building. - `HomeViewModel.cs`: Simple section ViewModel using functional-reactive commands. ## When to Use This skill is applicable to execute the workflow or actions described in the overview. ## Limitations - Use this skill only when the task clearly matches the scope described above. - Do not treat the output as a substitute for environment-specific validation, testing, or expert review. - Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
