Vertical Slice Architecture

on YouTube ↗01h 02m

" summary

Shifts layered apps into per-feature code where each action is a request/handler/response class, registered with MediatR, using AutoMapper projections or raw SQL/EF Core/Dapper for reads and handlers that directly call infrastructure for writes. Adds pipeline behaviors for transactions, retries and logging, uses FluentValidation for request checks, pushes complex rules into domain objects, and relies on integration tests for handlers and unit tests for domain. Results: smaller merge conflict surface and more maintainable features.
