MVVM Patterns in Avalonia

Complete guide to MVVM patterns using CommunityToolkit.Mvvm in Avalonia applications.

What I do

• Guide implementation of ViewModels with ObservableObject base class
• Show how to create observable properties with [ObservableProperty] attribute
• Demonstrate command patterns with [RelayCommand] including async and CanExecute
• Explain View-ViewModel mapping using DataTemplates (critical for navigation)
• Show dependency injection patterns for passing services to ViewModels

When to use me

Use this skill when you need to:

• Create new ViewModels for Avalonia views
• Implement observable properties that notify the UI of changes
• Add commands to handle user interactions (button clicks, etc.)
