Clean architecture with CQRS and MediatR in Asp.Net Core

In this video we tackle a very specific approach to clean architecture in #AspNetCore: with CQRS and MediatR. We kick off the video on the blackboard explaining what CQRS and the mediator pattern are and then we jump into code and implement these concepts in a new solution.

I like how the box of the last command was so bad that the autocorrect didn't get that it was a square 😂. Amazing explanation, Dan.

I was watching 3 or more videos before I hit this one. I didn't understand the pattern using previous videos & this one really helped me to pick up the topic. Thank you!

I use almost identical to this architecture and it's quite useful and incredibly easy to do unit testing.

Great content! Thanks for your time to share your thoughts.

Thnk you so much! But what about usage of Requests and Responses along with a CQRS as DTOs? Do you have any videos about that Dan?

[curlybytes]

can we have the copy of the code on this one? thanks!

Thank you for the video. I really the way you explain and show things. I have a question about CQRS: For every single action on the controller we need a new class using mediatR? Like, if I have 10 different querys, I would have 10 different classes? Thank you very much.

Nice to see another Rider aficionado! 👍

Maybe a dumb question, where is forecast request object coming from? . Currently in php, this is taking the most of our time, mapping a (psr) request to a command with valid values.

please tell me which tool u r using to draw with pen, that is correcting the shapes.. please pelase pelase

fantastic video . good luck and please record more videos

Sorry for the question but in clean architecture we need to use a presenter to convert and prepare viewmodels to show in our UI. Why you don't use it??

[alpachinois]

A recruiter asked me why commands are in Application layer. What should I say?

[aminkhosravi]

How can we do unit testing for such a controller?

[shubhankarpaul]

Application should not depend on Infrastructure.... the clean architecture clearly fails in this case
