In Part 1 of this series, we discussed the fundamentals of CQRS (Command-Query Responsibility Segregation) and the Mediator pattern in ASP.NET Core, focusing on separating read and write operations for a cleaner and more maintainable architecture. Now, in Part 2, we’ll dive deeper into advanced techniques to enhance the CQRS and Mediator setup. We’ll explore FluentValidation, cross-cutting concerns, and how to optimize both the command and query sides.
By the end of this post, you’ll be equipped to handle more complex scenarios using CQRS and Mediator in ASP.NET Core, ensuring your application is scalable, maintainable, and ready for production.
1. Adding Validation to CQRS Commands
One of the common requirements for handling commands is input validation. Without proper validation, invalid commands can affect the application’s state. Here, we’ll integrate FluentValidation, a popular .NET library for declarative validation.
