Should I merge Generic.xaml in App.xaml instead?

No, that is considered an anti-pattern for control libraries because it breaks encapsulation and often causes styles to fail when the library is referenced by other applications.

Why does my Custom Control style still not show up after configuration?

Ensure you have also overridden the DefaultStyleKeyProperty in the control's static constructor and that the TargetType in your XAML matches the control type exactly.

What does ResourceDictionaryLocation.SourceAssembly do?

It specifies that the generic resources, specifically Themes/Generic.xaml, are located within the same assembly where the control is defined.

Why is ThemeInfo important in WPF?

It tells the WPF resource engine exactly where to look for theme-specific and generic styles, ensuring your CustomControls render correctly even when used in external projects.

Configures the ThemeInfo attribute in WPF projects to ensure custom control styles load automatically and correctly across assemblies.

This skill automates the configuration of the ThemeInfo attribute within AssemblyInfo.cs, a critical step for WPF Custom Control Library development. It ensures that Themes/Generic.xaml is properly discovered and loaded by the WPF resource engine, preventing common issues where styles fail to apply when controls are consumed by external applications. By implementing these best practices and avoiding common App.xaml anti-patterns, developers can build robust, self-contained, and professional-grade WPF UI components that work seamlessly across different projects.
