### Custom Control Migration Support

For applications with custom controls inheriting from `WebControl` or `CompositeControl`, the library provides:

- **Adapter Classes**: `WebControl`, `CompositeControl`, and `HtmlTextWriter` classes that enable minimal-change migration
- Base attributes (ID, CssClass, Style) are automatically applied - no manual intervention needed
- **Roslyn Analyzers**: The `BlazorWebFormsComponents.Analyzers` NuGet package provides automated code analysis and fixes:
- **BWFC001**: Detects public properties missing `[Parameter]` attributes with automatic fix

See the [Custom Controls Migration Guide](docs/Migration/Custom-Controls.md) for details.
