Go here: https://bit.ly/3SXlzSt You've probably heard—MediatR is going commercial. If you're using it in your Clean Architecture template (like I did), it might be time to explore alternatives. In this video, I’ll walk you through a full MediatR-free CQRS implementation using custom `ICommand`, `IQuery`, and handler interfaces. ✅ We’ll cover: Why I decided to remove MediatR How to build your own CQRS abstractions Replacing ISender with explicit handler injection Manual DI vs automatic scanning using [Scrutor](https://www.nuget.org/packages/Scrutor) Fully working Command & Query pipeline without third-party libraries You'll see how to: Refactor a .NET API endpoint from MediatR to your own handler Register handlers manually and automatically Handle generic result types for commands and queries 👉 Want to skip ahead and use the updated template?
