Ported Windows Apps

UWP sample applications migrated to WinUI 3 (Windows App SDK).

These are work-in-progress migrations intended to:

• Demonstrate modern WinUI 3 patterns (MVVM with CommunityToolkit, SDK-style projects, .NET 8)
• Document migration pitfalls for developers and AI tools
• Serve as reference implementations for the UWP → WinUI 3 migration guides on Microsoft Learn

Samples

Sample	Original (UWP)	Status	Key Technologies

Customers Orders Database	Windows-appsample-customers-orders-database	📋 Assessment	Already migrated upstream; guide documents patterns

Migration Guides

Each sample includes a MIGRATION-GUIDE.md documenting:

• API substitutions performed
• Controls that required rework (no direct equivalent)
• Pitfalls for developers and LLMs
• Architecture decisions and rationale

Common Patterns

All migrated samples follow these conventions:

• .NET 8 with net8.0-windows10.0.22621.0 target
• Windows App SDK 1.6
• CommunityToolkit.Mvvm 8.4.0 (source generators, ObservableObject, RelayCommand)
• SDK-style .csproj (auto-include, no explicit file listings)
• Static App.MainWindow pattern for window handle access
• System.IO for file operations (works packaged and unpackaged)

Status

⚠️ These samples are work-in-progress. They compile and demonstrate the architecture, but may need refinement before serving as polished public samples.
