# XAML and C# Cross-Platform Development (for Avalonia)

Use this skill to produce reflection-minimized, modern, fast Avalonia apps that stay maintainable across desktop, browser, and mobile targets.

Primary entry for the full reference set:
- `references/compendium.md`

## Workflow

1. Define app scope, API surface, and lifetime model.
- Read `references/00-api-map.md`.
- Read `references/01-architecture-and-lifetimes.md`.
- Choose the root lifetime first (`IClassicDesktopStyleApplicationLifetime` or `ISingleViewApplicationLifetime`) and use `IActivatableLifetime` as an optional feature hook when needed.

2. Lock platform bootstrap and build pipeline before UI work.

4. Build view composition, locator strategy, and interaction routing.
- Read `references/11-user-views-locator-and-tree-patterns.md`.
- Read `references/38-data-templates-and-idatatemplate-selector-patterns.md`.

- Read `references/58-textbox-editing-clipboard-undo-and-input-options.md`.
- Read `references/34-dragdrop-workflows.md`.
- Keep routed-input handling thin and deterministic; prefer command/state dispatch.

5. Author properties, styles, themes, resources, and assets as one system.
- Read `references/16-property-system-attached-properties-behaviors-and-style-properties.md`.
- Read `references/04-styles-themes-resources.md`.

- Read `references/35-path-icons-and-vector-geometry-assets.md`.
- Read `references/28-custom-themes-xaml-and-code-only.md`.
- Read `references/66-professional-ui-design-tokens-and-themes.md` and use the detailed topics under `references/professional-design/README.md` for professional UI/UX systems, token architecture, typography, spacing, command language, quality gates, information architecture, navigation, forms, dense workflows, localization, BiDi, touch/gesture behavior, responsive layout, stateful feedback, motion, composition, overlays, and component variants.
- Read `references/67-microsoft-fluent-design-and-fluenttheme.md` and use the detailed topics under `references/fluent-design/README.md` when the user wants Microsoft Fluent design, FluentTheme palette customization, density tuning, brand/token mapping, Fluent shells, language-system guidance, localized/inclusive content patterns, navigation, notification language, materials, motion, composition, touch/gesture behavior, Fluent-specific interaction guidance, or Fluent/public icon-system guidance in Avalonia.
- Keep property metadata, style selectors, media rules, and resource lookup predictable.

6. Implement controls and window surfaces.
- Read `references/10-templated-controls-and-control-themes.md`.

- Read `references/54-native-menu-and-native-menubar-integration.md`.
- Read `references/55-tray-icons-and-system-tray-integration.md`.
- Read `references/56-managed-notifications-and-window-notification-manager.md`.
- Read `references/52-controls-reference-catalog.md` for per-control API quick lookup.
- Read `references/25-popups-flyouts-tooltips-and-overlays.md`.
- Separate control contract, template parts, and platform-specific window/popup behavior.

7. Implement layout and large-data item presentation.
- Read `references/30-layout-measure-arrange-and-custom-layout-controls.md`.
- Read `references/21-custom-layout-authoring.md`.
- Read `references/20-itemscontrol-virtualization-and-recycling.md`.
- Read `references/57-scrollviewer-offset-anchoring-and-snap-points.md`.
- Use invalidation discipline (`InvalidateMeasure`/`InvalidateArrange`) and recycling-aware templates.

8. Add motion, compositor effects, and custom rendering only where needed.
- Read `references/12-animations-transitions-and-frame-loops.md`.
- Read `references/15-compositor-and-custom-visuals.md`.
- Read `references/14-custom-drawing-text-shapes-and-skia.md`.
- Read `references/37-shapes-geometry-and-hit-testing.md`.
- Read `references/59-media-colors-brushes-and-formatted-text-practical-usage.md`.
- Read `references/61-rendering-and-interop-boundaries-opengl-vulkan-framebuffer.md` for advanced interop only.

12. For web-to-desktop migration work, map HTML/CSS idioms explicitly.
- Read `references/62-html-css-to-avalonia-modern-ui-conversion-index.md`.
- Use detailed topic docs under `references/html-to-avalonia/` (index at `references/html-to-avalonia/README.md`, currently `00`-`39`).

13. For Windows desktop migration work, map WinForms idioms explicitly.
- Read `references/63-winforms-to-avalonia-modern-ui-conversion-index.md`.
- Use detailed topic docs under `references/winforms-to-avalonia/` (index at `references/winforms-to-avalonia/README.md`, currently `00`-`38`).

14. For XAML desktop migration work, map WPF idioms explicitly.
- Read `references/64-wpf-to-avalonia-modern-ui-conversion-index.md`.
- Use detailed topic docs under `references/wpf-to-avalonia/` (index at `references/wpf-to-avalonia/README.md`, currently `00`-`45`).

15. For Windows App SDK / WinUI migration work, map WinUI idioms explicitly.

- Use detailed topic docs under `references/winui-to-avalonia/` (index at `references/winui-to-avalonia/README.md`, currently `00`-`66`).

## Public API Coverage

Use curated app-building API guidance first:
- `references/00-api-map.md`

For a generated, broad signature index of app-building surface:
- `references/api-index-generated.md`

Regenerate index after repo upgrades or if API drift is suspected:

```bash
python3 scripts/generate_api_index.py \
  --repo <path-to-avalonia-repo> \
  --git-ref 11.3.12 \
  --output references/api-index-generated.md
```

Search patterns for the large generated index:
- `rg -n "AppBuilder|ApplicationLifetime|StartWithClassicDesktopLifetime" references/api-index-generated.md`
- `rg -n "CompiledBinding|ReflectionBinding|AvaloniaXamlLoader" references/api-index-generated.md`
- `rg -n "AvaloniaRuntimeXamlLoader|RuntimeXamlLoaderConfiguration|ResourceInclude|StyleInclude" references/api-index-generated.md`
- `rg -n "UseWin32|UseX11|UseAvaloniaNative|UseBrowser|UseAndroid|UseiOS" references/api-index-generated.md`

## Execution Rules

- Prefer compiled XAML and compiled bindings for production.
- Default to XAML-first examples and guidance; provide code-only UI construction only when the user explicitly requests it.
- Treat `RequiresUnreferencedCode` and `RequiresDynamicCode` APIs as opt-in tradeoffs.
- Keep binding paths typed (`x:DataType`) and avoid runtime parser fallbacks when equivalent typed APIs exist.
- Use platform option classes through `AppBuilder.With<T>(...)` instead of ad-hoc globals.
- Preserve clear separation: startup wiring, view definitions, viewmodel/reactive state, and styling/resources.
- Include end-to-end examples in responses when asked for architecture changes.
