Avalonia ViewModels with Zafiro

Selective Reading Rule

Start with:

• references/senior-master-standard.md
• references/usage-routing.md
• references/quality-checklist.md

Then load only the inherited docs, scripts, assets, or examples that match the user's actual task.

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.
