Anatomy of a Slice in Production: Handlers without Interfaces, EF Core without Repositories and Decoupled Events (Part 2)
En la Parte 1 de esta serie , exploramos por qué Clean Architecture tradicional suele agotar a los equipos con su laberinto de proyectos y capas. Vimos la filosofía de Vertical Slice Architecture (VSA) : la complejidad se paga por slice, no por proyecto , y cómo organizar Minimal APIs limpias y auto-descubiertas. Pero ahora viene lo bueno: abrir el capó del motor y escribir código de producción .…
The article discusses the Vertical Slice Architecture (VSA) approach in .NET development, specifically how to structure a use case to avoid large, unmanageable files. It presents an example of a "Create Product" use case, where all related code, including contracts, validation, and logic, is contained within a single file, `Features/Products/CreateProduct.cs`.
This approach eliminates the need for interfaces and generic repository patterns, instead using a primary constructor to inject dependencies. The article argues that this structure improves maintainability and testability, and that interfaces should only be used when there are multiple implementations, such as at system boundaries.
