In this video, I show you how I built a custom domain event dispatcher to replace MediatR’s IPublisher.Publish functionality — without breaking my application layer. You’ll learn: How MediatR handles domain events under the hood How to define IDomainEvent and IDomainEventHandler interfaces Wiring up the dispatcher with EF Core and SaveChangesAsync Using reflection and scoped DI to invoke handlers Trade-offs (performance, type safety, complexity) Whether you're building a Clean Architecture app or want more control over your CQRS stack — this guide will help you move away from third-party dependencies like MediatR.
