To structure AvaloniaUI CustomControls, use a dedicated Themes directory containing Generic.axaml and your control classes. This layout enforces a clear separation of concerns between control visuals and behavior, enabling scalable UI architecture.

Organize Generic.axaml within a central Themes directory. This placement standardizes ControlTheme definitions for your CustomControls, ensuring consistent modular theming and reusable component styling across the AvaloniaUI project.

You separate visuals from behavior by defining appearance in AXAML ControlThemes and logic in code-behind classes. This architecture isolates UI styling from functional behavior, creating highly reusable and themeable Avalonia components.

You need a dedicated Themes folder when starting a new AvaloniaUI project or building standalone styling workflows. It centralizes ControlTheme management and Generic.axaml placement, ensuring strict separation of visual concerns from control behavior.

Yes, this CustomControl architecture applies to both new AvaloniaUI desktop applications and standalone control styling workflows. It defines the standard solution structure, guiding project layout and modular theming for reusable components.

Using ControlTheme for Avalonia CustomControls enforces modular theming and a clear separation of concerns. It standardizes visual definitions in Generic.axaml, preventing scattered inline styles and ensuring scalable, reusable component architecture.
