WPF
Build and modernize WPF applications on .NET with correct XAML, data binding, commands, threading, styling, and Windows desktop migration decisions.
Trigger On
- working on WPF UI, MVVM, binding, commands, or desktop modernization
- migrating WPF from .NET Framework to .NET
- integrating newer Windows capabilities into a WPF app
- implementing data binding, styles, templates, or control customization
Workflow
- Confirm Windows-only scope — WPF is Windows-only even when the wider .NET stack is cross-platform
- Apply MVVM pattern — keep views dumb, logic in ViewModels, use commands
- Manage data binding explicitly — choose correct binding modes, validate at runtime
- Use styles and templates deliberately — keep UI composable, avoid page-specific hacks
- Handle threading correctly — use Dispatcher for UI updates, async/await for long operations
- Validate both designer and runtime — XAML composition failures often surface only at runtime
Deliver
- cleaner WPF views and view-model boundaries
- safer binding and threading behavior
- migration guidance grounded in actual Windows constraints
- MVVM pattern with testable ViewModels
Validate
- binding and command flows are explicit
- code-behind is not carrying hidden business logic
- Windows-only assumptions are acknowledged
- threading and dispatcher usage is correct
- styles and resources are properly organized
