One of the best thorough tutorials on KZbin. The best part is that the tutorial enforces best practices DI, mocking, data mapping and much more. Thank you for the awesome work....

[@MegaTeaque]

With synchronous switching from CreatedAtRoute to CreatedAtAction does not require the additional Name field in the GetCommandById Method. 2:34:01 However, when using a Async Methods CreatedAtAction doesn't work. Also, You can use inheritance to implement CommandUpdateDto 2:48:00 e.g. public class CommandUpdateDto : CommandCreateDto {}

I really like that you don't edit the video to 'hide' any mistake. This can teach us a lot, as for sure we are going to find ourselves in similar situations. Keep up the good work!

[@WolfieVenturi]

This is seriously great. Keep these coming!

[@DS-ji1cz]

It took me nearly 8 hours to watch and do it on my own. I feel confident about my basics now. Thanks Les.

[@NicoFlyn]

I am writing to you from Argentina, I want to thank you. With the clear way to explain the topics and follow your steps throughout the video, with another plus in my studies. I got my first job with .NET. Thank you!

[@DarthKamci0]

This course helped me immensely! I have one suggestion - how about updating the video with chapters (shown on the red bar)? KZbin added the functionality in May and I think including them here would improve the experience a lot and help come back to the vid if you don't have the time to digest it in one sitting.

[@doctorrusty6494]

It is THE BEST tutorial for Web API using .Net Core 3.1 that I've ever seen! Simple, trully step-by-step and easy to follow, yet comprehensive and following all modern standards and best practices! Keep up the good work Les - can't wait for more content! I might even buy your book...

[@wordonice4457]

It's 2:04AM. Just finished this. Started sometime around the evening. Was so worth it. Thank you very, very much, Les!

[@curtmantle7486]

I have an Apress Access account and I paused this video to reference a book I had previously downloaded on APIs in .NET Core. After a few minutes the penny dropped that I was referencing your book while watching your video. Great work on both counts.

[@papillonx101]

As for me , this is by far the best tutorial on Web API so far(and I have seen different of them). Great work!

Oh Hi Kenan - thanks for awesome feedback - made my day! Cheers, Les

Hey man! I am Brazilian and I live in Canada. I don't have the habit of leaving comments, but your video helped me a lot, extremely complete and I love the way you always stop and explain what you're doing. Much more than a tutorial, this is a lesson. You helped me a lot! Thank you!

[@alirezahamidi893]

That Was Amazing I Never thought i can get a full learning of dotnet core in 3 hours. I Watched it second by second and Thank you for what you teached me

[@Office-Clerk]

It is not a full learning of dotnet core.

[@georgeb1951]

Just want to say i learned more about Core with EF in the first 30 minutes of this tutorial than in any other video I've viewed..... very well done!

[@TheDarkZeroGame]

moment you started to speak, i knew i was gonna enjoy learning from you. I can listen to you read a phone book!

[@parvezborkar4773]

Just completed your entire course, All I can say is just amazing. People can actually go ahead and copy paste your code in theirs in the interest of saving time. Extremely well explained and kept the code to easiest to understand.

[@f0rty7even9]

a quick tip; instead of having to restart your dotnet server each time you make an update to your code, you can use `dotnet watch run`. this will restart your server automatically every time you update your code =)

[@binarythistle]

Great tip thanks!

Hi Lee, long comprehensive vid - had to watch in few stages but was fantastic to help me see the transition from using .NET classic stack to build DIY web services - to current tooling and practice. Was nice to see lots of familiar concepts and challenges being addressed in intuitive way. I like your pace and no nonsense approach. Really appreciate the effort and contribution to the greater good. As we say in Wales - cheers butt :)

[@shaughngulliver8704]

Les, you saved me big time. Your videos are great, I almost lost a client because of me not understanding Azure and WEB API, two of your videos showed me everything that I needed, and now they are up and running. Thank you so much.

[@nselsmark]

Thank you so much for this course! I have been looking for a "best practice" course, that doesn't just use the controller and such. I can't thank you enough man! Great explanations and everything! :)

[@savaladaojr]

Hi Les, this is the most amazing video I saw on KZbin related to the .NET Core API. You go through the topics smoothly and with mastery. It was my first access to your channel, and for sure I'll be a frequent visitor! Millions of thumbs up to you.

[@avi062]

I think it's time people should learn more about enterprise standard like this one. Topic on Identity, OAuth 2.0, Error handlers, loggers and schedulers would be great.

[@TheSlapOff]

Yeah, this would be great.

[@ashishkhatiwada7828]

I am not a security expert but Brock Allen is channel9.msdn.com/Events/DEVintersection/DEVintersection-2016/DEV09 and In fact Brock Allen Made Identity server.. Which will use OAuth2.0 for authorization..

[@Cyclopath83]

Indeed, Authorization and Authentication would be great. Also, a multi-model app would be great. For example, have a model "command" and a model "platform". Just to see how they can interact. And versioning? Since the contract is fixed per version, when you want to add functionality, you should create a new version.

[@arunece100]

Seen any tutorial like that?

[@jan-willempannekoek]

Thanks Les Jacksen! Great informative video. However, I do have a question. How should I go about changing the format the api gives back? It's now a JSON, but say I want it to return a GeoJSON format or something, how should I go about making that happen?

Thank you so much for this tutorial! Doing this on a text editor, as opposed to an IDE, made this tutorial much more educational.

As an adept fan of frontend technologies, I never liked venturing into backend. But alas, circumstances forced me into a backend learning environment, and your video was of tremendous help to me; easing my understanding and the concept of how APIs work and what backend development was all about (especially in .NET). Great work and thanks for the tutorial

Hello Les, it was a great study of .net core rest API to learn easily. So I am excited about new studies which will come from you. Hope you are doing well. Please take care of yourself nowadays in Australia. Btw, I just want to write my solution about the 'homework'. I think I'd rather use one single data transfer object for all crud operations. If there is only one dto then it will be fine as well. This sounds, it isn't a good idea while creating an object because of the required properties, I think it still the best option. Best wishes from Istanbul.
