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
