This is literally a gem of a video. I am a beginner and I wanted to learn how to make the web applicatios APIs in dotnet . I had started watching tutorials, but I was completely confused about where to begin and what the proper learning structure should be. I couldn’t even understand how to take the first step.
But this video and the way everything is explained makes learning so enjoyable. Things become so easy when you learn from a great teacher. I am genuinely enjoying this video... Thankyou so so so so much!!

Cant even explain how great the lessons are. You actually go into detail on how things are connected, setup, and most importantly what they mean. I have seen too many videos where they say, "add this" and I have to pause the video and watch another or find out on my own what something is doing which throws me off my process and flow. Just got to the point in the frontend tutorial where you sent us here and am soo excited to get more knowledge on building my own rest API as a few companies I have talked to asked me if I have built my own before.

The are so many useless tutorials on youtube but Julio is the goat, very useful and informative especially when you really wanna learn how things are connected on the backend.

I am here in July 2026 with dotnet 11. New to the whole concept but this guy Julio has simplified things for me a great deal. Can't believe i am getting this knowledge for free from the University of Youtube.😍 Thanks bro!

Best .NET course on YouTube

@zaidmakani5037 2 years ago

Outstanding content Julio. Very few online courses teach minimal apis from scratch. Most of them still teach Controller based apis with sqlserver.
The best part about this tutorial was the use sqlite which is hassle free especially for non windows users who don't have MS Sql server readily available.
Thanks.

Julio, your courses are phenomenal, you explain the best practices and concepts in such a simple manner that listening to your videos is almost addictive. I couldn't find anyone else quite like you, doesn't matter what language they use. I'm learning so much about professional software development in general, while at the same time exploring C# which is new to me. I will highly recommend all your free and paid content to anyone interested in C#

@namanjoshi2528 2 years ago

Thanks a lot, Julio, this tutorial has really helped me to understand ASP.NET core, minimal API, please, don’t stop marking such videos series, its really beneficial for professional like me who are using .NET and .NET framework. Thanks a ton, will be looking forward for more videos series :)

Absolutely brilliant course, way better than many paid options for learning the topic! I love that you explain everything so clearly and remove any sort of "black box" feeling to .NET, it really helps with understanding it practically.
