The mini course is here, I guess I'll watch it on my lunch break.

[cybul]

Mini course for almost 9 hours when I was expecting like 20-30 minutes. Love you guys.

[DevMentorsEN]

Sorry for the delay, but this got edited and rendered to long!

[hunterwebapps]

This is very high quality, and strikes a good balance of approachable with advanced topics.

[vivekkaushik]

The fact that not only he recorded an almost 9 hour "mini" course, edited it and provided Chapter as well is mind-blowing for me. So much time and effort must have gone into this. Thankyou so much. As an upcoming Senior C# dev, this will really help me out. Subbed.

[rajbh]

YOU ROCKS BRO. After the 24 hours microservices course, this is the best course by you guys. KEEP up the good work

[qiueodl]

Wow! I didn't have time to finish watching it yet, but that's definitely a very useful course. Great job, Derek. Thanks!

[uzzojny]

This deserves more, way more likes and views. Seriously good content.

[acedonk]

About to embark on my first Clean Architecture project, this was a perfect primer to get into the right mindset!

[dp-bhatt]

Thank you very much. The content is really awesome. I've watched the whole video continuously for almost 9 hours. hats off to you.

[szymontomczyk]

During watching the video, several questions or even concerns came to my mind and then all of a sudden you were addressing each of it :) even without asking!
Very well prepared course, thank you :)

[anisdjer]

Wow, this course is incredibly comprehensive and informative! I'm so grateful for the time and effort you put into creating it. I've been learning about clean architecture for a while now, but this video has helped me to understand it so much better.

I especially appreciate the way you explained the DDD in a way that was easy to understand. And the examples you provided were really helpful. I also liked the way you structured the video, with clear sections and transitions.

Overall, this is an amazing video that I highly recommend to anyone who wants to learn more about clean architecture. Thank you so much for sharing your knowledge!

[johnhmuller]

Thanks for this course, completed it, learned a lot! :)

[hazeleclipse]

Great video. I appreciate the detailed explanation of your thought process behind decisions as well as possible alternate decisions.👍👍

[shashikantpawar]

Thank you for this series. I am at 45.10 min and have gone through the theory till now

[Keiktu]

Can't believe that this is free, thank you!

[Hiad]

Amazing course. Thank you for your effort.

[branislavpetrovic]

Are you kidding? This comprehensive and advanced course for free, all the best to you.

Thanks Dariusz and DevMentors!

[leandrotapia]

Definitely a great course! I totally agree that clean architecture is not a silver bullet as there is no such thing as a golden hammer at all! But I think sometimes developers don't like "the extra boilerplate" just because they don't give themselves a chance to build an application where the model isn't just anemic objects, which breaks the encapsulation and leaves the business rules in "SomeEntityService" classes with a hundred dependencies related to completely different use cases, which also adds a lot of complexity to the tests. Also, calling those anemic objects "the domain", rather DTOs or persistent entities. I really appreciate the high quality course you have shared! Greetings from Argentina! 🇦🇷

It's 😍, I don't know how i can thank you for this very meaningful content
