Provides expertise in building modern Windows desktop applications using WinUI 3, WPF, and Windows App SDK. Specializes in XAML-based UI development, MVVM architecture, native Windows integration, and modern packaging with MSIX.

When to Use

  • Building Windows desktop applications with WinUI 3 or WPF

  • Implementing MVVM architecture for Windows apps

  • Creating XAML layouts and custom controls

  • Packaging applications with MSIX

  • Integrating with Windows features (notifications, taskbar, system tray)

  • Migrating WPF applications to WinUI 3

  • Implementing Windows-specific features (jump lists, live tiles)

  • Building Microsoft Store-ready applications

Quick Start

Invoke this skill when:

  • Building Windows desktop applications with WinUI 3 or WPF

  • Implementing MVVM architecture for Windows apps

  • Creating XAML layouts and custom controls

  • Packaging applications with MSIX

  • Integrating with Windows features (notifications, taskbar)

Do NOT invoke when:

  • Building cross-platform apps → use mobile-developer or electron-pro

  • Console applications → use appropriate language skill

  • PowerShell GUI → use powershell-ui-architect

  • Web applications → use appropriate web skill

Decision Framework

Windows App Task?
├── New Modern App → WinUI 3 with Windows App SDK
├── Existing WPF App → Maintain or migrate to WinUI 3
├── Cross-Platform Priority → Consider .NET MAUI
├── Enterprise Internal → WPF with proven patterns
├── Store Distribution → MSIX packaging required
└── System Integration → P/Invoke or Windows SDK APIs

Core Workflows

1. WinUI 3 Application Setup

  • Create project using Windows App SDK template

  • Configure Package.appxmanifest for capabilities

  • Set up MVVM infrastructure (CommunityToolkit.Mvvm)

  • Implement navigation and shell structure

  • Create reusable control library

  • Configure MSIX packaging

  • Set up CI/CD for Store or sideload distribution

2. MVVM Implementation

  • Define ViewModels with observable properties

  • Implement commands for user actions

  • Create services for data and business logic

  • Set up dependency injection container

  • Bind Views to ViewModels in XAML

  • Implement navigation service

  • Add design-time data for XAML preview

3. MSIX Packaging

  • Configure Package.appxmanifest

  • Define application identity and capabilities

  • Set up visual assets (icons, splash)

  • Configure installation behavior

  • Sign package with certificate

  • Test installation and updates

  • Submit to Microsoft Store or deploy internally

Best Practices

  • Use WinUI 3 for new development, WPF for legacy maintenance

  • Implement MVVM strictly for testability and separation

  • Use x:Bind for compile-time binding validation

  • Leverage Community Toolkit for common patterns

  • Package with MSIX for modern installation experience

  • Follow Fluent Design System for consistent UX

Anti-Patterns

  • Code-behind logic → Move to ViewModels

  • Synchronous UI operations → Use async/await for I/O

  • Direct service calls from Views → Go through ViewModels

  • Ignoring DPI awareness → Test at multiple scale factors

  • Missing capabilities → Declare required capabilities in manifest
