Use before committing to catch issues that the compiler and UI tests won't find.\"\n---\n\n### When to Use\n\nRun a code review **after the app builds and before committing**. This catches quality issues that aren't build errors and aren't visible in UI tests — patterns that compile and run but are wrong, fragile, or slow.\n\n### How to Review\n\nRead through the project's XAML and C# files and check each section below. The `Microsoft.WindowsAppSDK.Analyzers` Roslyn analyzer ships with the `winui-dev-workflow` skill and is injected when `BuildAndRun.ps1` calls project-mode `winapp run`. The wrapper supplies a temporary file through the environment-backed MSBuild `CustomAfterDirectoryBuildProps` hook, preserving SDK composition and each project's normal `Directory.Build.props` discovery (including referenced projects), then restores the environment and removes the temporary file. Plain `winapp run`, `dotnet build`, and Visual Studio do **not** load the analyzer automatically; to enable it outside the wrapper, add the `<Analyzer Include=\"...\" />` and `<Import Project=\"...\" />` entries to the project's own `Directory.Build.props` (or wait for the planned NuGet package).\n\nThe analyzer catches a curated set of WinUI 3 / Windows App SDK issues with categorized 4-digit IDs:\n\n* **WUI0xxx** — UWP → WinUI 3 API compatibility (`UwpXamlNamespace`, `Window.Current`, `CoreDispatcher`, `GetForCurrentView`)\n* **WUI1xxx** — Migration-table data-driven hints (UWP API has WinAppSDK equivalent, no equivalent, feature-area hint)\n* **WUI2xxx** — Runtime / layout / XAML pitfalls (raw `TabView` content, nested `x:Bind` without fallback, `x:Bind` without `Mode`, null `Converter`, missing `AutomationId`, attached-property syntax)\n* **WUI3xxx** — MVVM patterns (old `[ObservableProperty]` field syntax)\n* **WUI4xxx** — Interop (`WebView2` not initialized, removed ONNX Runtime GenAI APIs `WUI4101`-`WUI4103`)\n\nEvery diagnostic ships at `Warning` severity (no rule is `Error`) and includes a `helpLinkUri`. Suppress noise with `#pragma warning disable WUIxxxx` or `<NoWarn>` as usual — the analyzer's `SuppressionTests` verify that pragma suppression round-trips correctly.\n\n### MVVM Compliance\n\n- [ ] ViewModels extend `ObservableObject`, use `[ObservableProperty]` partial properties (not fields)\n- [ ] Commands use `[RelayCommand]` attribute, not manual `ICommand` implementations\n- [ ] No UI types in ViewModels (`SolidColorBrush`, `Visibility`, `BitmapImage`) — these belong in converters or XAML\n- [ ] No business logic in code-behind — only navigation, dialog coordination, and event wiring\n- [ ] `async Task` for async methods, `async void` only for event handlers\n- [ ] Never replace `ObservableCollection<T>` — use `.Clear()` + re-add\n\n### x:Bind and Data Binding\n\n- [ ] All bindings use `{x:Bind}`, not `{Binding}`\n- [ ] `Mode=OneWay` or `TwoWay` set explicitly — `OneTime` default causes blank UI for dynamic data\n- [ ] `x:DataType` set on every `DataTemplate` — required for compiled x:Bind\n- [ ] No nested nullable paths (e.g., `ViewModel.Selected.Name`) without `FallbackValue`\n- [ ] Command bindings can use OneTime (commands don't change) — don't add `Mode=OneWay` to `Command=\"{x:Bind}\"`\n\n### Accessibility\n\n- [ ] `AutomationProperties.AutomationId` on every interactive control (Button, TextBox, ComboBox, ToggleSwitch, ListView, NavigationViewItem)\n- [ ] `AutomationProperties.Name` on icon-only buttons and controls without visible text\n- [ ] Semantic controls (`Button`, `HyperlinkButton`) — not clickable `Border`/`TextBlock`\n- [ ] No information conveyed by color alone\n\n### Theming\n\n- [ ] All colors use `{ThemeResource}` brushes — no hardcoded `#FF0000` or `Color=\"Blue\"`\n- [ ] Typography uses built-in styles (`TitleTextBlockStyle`, `SubtitleTextBlockStyle`, `BodyTextBlockStyle`, `CaptionTextBlockStyle`) — no raw `FontSize`\n- [ ] Spacing uses 4px grid multiples (4, 8, 12, 16, 24, 32, 48)\n- [ ] Corner radius uses `ControlCornerRadius` / `OverlayCornerRadius` — not hardcoded values\n- [ ] Styles referenced with `{StaticResource}` not `{ThemeResource}` (except for brush usage sites)\n\n### Security\n\n- [ ] No secrets, API keys, or tokens in source code\n- [ ] No `Process.Start` with unsanitized user input\n- [ ] External input validated and sanitized before use\n- [ ] File paths from user input not used directly in `File.Delete` / `File.WriteAllText` without validation\n\n### Performance\n\n- [ ] Long or dynamic lists use `ListView`/`GridView` (virtualized), not `StackPanel` with `foreach`\n- [ ] `x:Load` for content that's not always visible (e.g., dialogs, secondary panels)\n- [ ] Heavy work off UI thread via `Task.Run` or `async/await` — never block UI\n- [ ] No `.Result` / `.Wait()` / `.GetAwaiter().GetResult()` — these deadlock the UI thread\n- [ ] `using` statements on all disposable objects (`Model`, `Tokenizer`, `InferenceSession`, `Generator`)\n\n### Globalization\n\n- [ ] User-facing strings use `x:Uid` in XAML and `ResourceLoader` in C# — not hardcoded\n- [ ] String resources in `Strings/en-us/Resources.resw` (not `.resx`)\n- [ ] Date/number formatting uses `CultureInfo.CurrentCulture` — not hardcoded formats\n- [ ] Layout supports RTL (`FlowDirection` inherited from root, no absolute positioning that breaks in RTL)\n- [ ] No string concatenation for user-facing messages — use `string.Format` or interpolation with resource strings\n\n### Review Report\n\nAfter reviewing, summarize:\n1. **Issues found:** List each with file, line, and what's wrong\n2. **Severity:** Error (must fix), Warning (should fix), or Note (could improve)\n3. **Suggested fixes:** Specific code changes for each issue\n\n### References\n\nFor detailed rules with code examples, see `references/quality-rules.md` — covers performance deep dives (x:Phase, layout optimization), security (PasswordVault, DPAPI, WebView2 hardening), accessibility (keyboard nav, screen readers), code quality (.editorconfig, naming), and globalization (x:Uid patterns, RTL, pluralization).\n","tagline":"Code quality review for WinUI 3 apps — MVVM compliance, x:Bind correctness, accessibility, theming, security, and performance.
