Thanks!

[@MohamadLawand]

Thank you for your support

[@hemkumardevarajan8164]

Great job on the presentation! The explanation and example were outstanding!!

[@yohanneskindu8794]

The level of detail, structure, and thought you've put into this content is truly remarkable. Fantastic video! Keep up the incredible work!

[@funshorts1248]

Amazing In depth and systematic explanation!

[@Andjelko999]

Straight to the point, simple and well explained! Well done!

[@moldovandorin6187]

this is the only clip where the author actually explains what's happening with the query, the handler and how mediator is using behind the scene the send method to process a query by the handler. Almost all the other videos are just mechanically showing ...this is the query, this is the handler, this is the mediator send ... bla bla bla with zero knowledge transfer. Thank you for the video Mohamad

[@runawayvon01]

Awesome content and detailed explanation for beginners.

[@andrei9218]

Hi, could you please create the notification part also?

[@SmittyRG]

Awesome content! The diagrams really help to understand the high-level concepts. Great job!

[@kellyncodes7421]

I love your videos. You explain things in detail, thank you so much. It will be very nice to create the notification path too.🎉🎉👍🤜🤛

[@nilokillian]

love you vids mate, keep it up!

[@nasermasri3816]

Super work!

[@Siddistaken]

Nice content and project idea end to end.

[@TellaTrix]

wow very nice skills to teaching. Thank you for this valuable content

[@xender2112]

Thanks, Mohammad.

[@sumithc.ekanayake1010]

Awesome content and good explanation. Thank you

[@blessdarah1256]

Yes I am also interested in the notifications part

[@TheImranbergi]

simply awesome explanation..

[@RoyZASTEROiD]

i like your videos like this, thank you.

[@Mohammad_Fael]

Good explaination but I think it'll be more clear if you name all classes with an end that refers to thier types like ____dto, ____command, _____handler,.....etc.

[@vaclavpernicka9471]

In the beginning in your slides you have dependencies between services. In the projects itself you just have controllers with business logic inside them. So it's kinda different. In the project IMO initial state should have a BLL.

[@kenjohnsiosan9707]

i use PHP for most of my projects, im new to .NET what is the benefit of using different connection string , does that mean there are multiple database? thanks

[@foonlam7134]

I'm see a lot if the Mediatr ir cqrs video show only simple crud operations. I have a complex app where i am processing messages that come in deoending on the message type. The method in my current controller has to call several other services and make http requests to third parties as well. My question is do i put all the method logic into the handler or do i need to create a separate command and separate handler for each if the service calls i make. If so, who will be orchestrating the process flow. If we put the whole logic into the handler are we not just moving the logic into another layer? This is where I'm confused. I wish someone would nake a video showing a bit more complexity in the handlers. I understand that they show the simple stuff so that we understand how it works but i need to know what the right approach is for complex logic

[@alexandermackintosh1755]

I think moving the business logic into its own layer is a benefit for sure, it's a big part of what using mediatR or services or specifications or whatever all have in common. The core business logic lives in one separated later away from all the interactions with the outside world (external APIs, databases, filesystems etc) so your handler/services/specifications are really obvious what their logic is and really easy to test. Whichever of these you pick I'm not convinced make too much difference tbh, as long as you pick atleast one of them!

[@SyedMubeenHussain-v9b]

best video

[@tarasiskiv9037]

I can't understand for what I need mediatR. So, if I keep all logic in my services, and in the controler's methods I just call methods from my services, why I need to use mediatR? It's easier to avoid mediatR. And also, it requires less code. Can someone explain me, why mediatR is better? Thanks

[@graphboss]

I wrote an answer to @foonlam7134 , maybe it will help you too.

[@syedakashmazhar1875]

I have the Exactly Same Question..

[@lindermannla]

Excelent content. Congratulations.

[@mkasem9408]

Hi, why you do mapping in Handlers and in Controllers?

[@okeluelazarus7062]

This video is perfect

[@onlylovelyvibes4467]

Amazing content

[@fahamakhan3682]

please create notification part as well, thank you.

[@alexandermackintosh1755]

Great video thanks! Is there any particular reason you used suffix 'request' instead of 'command' for the commands?

[@yoanantoniolopezrodriguez766]

Amazing...

[@shivaganga9148]

Awesome

[@EldonElledge]

Well done and informative. Thank you.

[@MohamadLawand]

Glad it was helpful!

[@imsupersir1134]

With the mediator pattern, are we creating a bottleneck?, by the way the content is good and the explanations is excellent, thanks a lot.

[@mousaabdelnabyahmed878]

There is a lot of English content and I noticed that you are smart, It would be great if your content was in Arabic, or at least had another Arabic content besides the english one. Thank you.

[@a.g.b7398]

can you explain the notification section

[@coreygerhardt9630]

Excellent videos. I've scoured this and its previous video to learn CQRS and Mediatr. I can't find how you made Delete and Update async though.

[@coreygerhardt9630]

Per usual, soon after I ask for help, I've figure it out. Great videos!!

[@chuonchuon7386]

Thank you 😀

[@andrei9218]

And if you could show how to add a new connection string for the queries

[@ShaZeGaming]

Hello, im try to learning from you. But in this class, i got the ' No service for type 'MediatR.IRequestHandler' has been registred' Error with MediatR. I try to fix this on the internet bu nothing work for me. Do you have any solution for it?

[@blessdarah1256]

Quick question: Does the new connection string improve on performance?

[@MilanZarathustra]

yes notification please

[@kek_1459]

Can you make a video about mediator notifications

[@mohammedabdalla6452]

Hello and thank you for the great content Can you put all of this in a small project and use the tdd approach Thank you again

[@kedarkulkarin78]

github code is not available it seems

[@dosovi4548bustayes]

IMO Unitofwork better :)

[@blessdarah1256]

UnitOfWork does the job just fine but CQRS really makes it easy to scale your API very well and really have a good separation of concerns.

[@dosovi4548bustayes]

@@blessdarah1256 too much code..

[@LuminoSkywalker]

Please explain your videos in Arabic ..... please speak Arabic
