This Skill provides clear guidance and patterns to avoid mixed responsibilities and tightly coupled logic by separating commands (writes) from queries (reads) when building .NET applications.
Add CQRS by creating command and query types, register MediatR and pipeline behaviors, and move controller logic into handlers to enforce separation of concerns.

Implement CQRS with MediatR in your .NET Clean Architecture project to separate state-changing commands from read-only queries using distinct request types and handlers. This enforces separation of concerns and prevents tightly coupled logic.
Configure MediatR pipeline behaviors by registering validation and logging behaviors in your .NET dependency injection container. Order the pipeline behaviors so validation executes before logging and transaction behaviors to fail fast on invalid command requests.
Use explicit naming conventions for CQRS commands and queries such as CreateOrderCommand and ListOrdersQuery. Match these with dedicated handler classes and specific request/response DTOs to maintain clarity across your Clean Architecture or VSA project structure.
Yes, the CQRS pattern with MediatR works with Vertical Slice Architecture. It provides guidance for folder organization and handler registration that applies to both Clean Architecture and VSA .NET projects organizing commands, queries, and pipeline behaviors.
Optimize read-only queries in a CQRS .NET application by applying AsNoTracking to your database read operations. This prevents the Entity Framework change tracker from overhead processing on ListOrdersQuery handlers returning paged responses.
FluentValidation is optional for implementing CQRS pipeline behaviors. The pattern supports optional FluentValidation integration alongside unit-of-work persistence patterns to validate command requests before they reach the handler execution phase.
