Description
Raise domain events directly from domain entities, following Clean Architecture and Domain-Driven Design (DDD) principles. Avoid raising events in the business logic of CQRS Handlers; instead, ensure that entities themselves are responsible for emitting events when their state changes.
Scope
- Implement domain events for key state transitions, such as
IsCompleteandIsChanging(e.g.,FormUpdatingEvent,FormUpdatedEvent). - Leverage
MediatRDomainEventDispatcheras infrastructure to dispatch events, and consider how EF Core can be used to process these events in a centralized and consistent manner. - Ensure that event raising is encapsulated within the domain model, not in application or handler logic.

Acceptance Criteria
- Domain events are raised from entities, not from CQRS handlers.
- State transitions like
IsCompleteandIsChangingare covered by events. - Event dispatching is handled centrally using infrastructure (e.g., MediatR, EF Core hooks).
- Code is clean, maintainable, and follows SOLID and DDD best practices.
