Class CompositeViewActivateChild

Activates a child within a composite view — the business operation behind a navigation rail swapping the content area. It resolves the target composite from the registry and tells it to activate the requested child; the composite owns the visibility mechanics.

Syntax

public class CompositeViewActivateChild : ISyncUseCase<CompositeViewActivateChildInput>, IUseCase

Remarks

Keeping this as a use case (rather than wiring the signal straight to the view) puts the navigation decision in the business layer, so the rule "activating a child swaps the content" is expressed independently of Unity and is unit-testable against a fake ICompositeViewService.
