SKILL.md
Avalonia Styling and Resources
Start with:
../../references/04-styles-themes-resources.md../../references/16-property-system-attached-properties-behaviors-and-style-properties.md../../references/17-resources-assets-theme-variants-and-xmlns.md
Load these when needed:
../../references/28-custom-themes-xaml-and-code-only.md../../references/43-xaml-in-libraries-and-resource-packaging.md../../references/35-path-icons-and-vector-geometry-assets.md
Workflow
- Decide which behavior belongs in properties, styles, templates, or resources.
- Keep selectors and theme-variant boundaries predictable.
- Package shared resources cleanly when the code lives in libraries.
- Make lookup order and override points explicit before adding more layers.
Rules
- Keep property metadata and style ownership clear.
- Prefer stable resource keys and predictable override layers over ad-hoc duplication.
- Use code-only themes only when XAML does not fit the requirement.
