this is one of the best tutorials I have seen on RU-vid or any platform really. Thank you very much for taking the time to share your knowledge.

My Friend, I have travelled very far to find this PERFECT video explaining .NET core MVC!! I'm a full stack JS dev, its surprising how complicated other people make .NET core MVC seem. What a great teacher and coder! Thank you

One of the best tutorials to understand the basics of the whole thing (.Net Core , MVC, EF and API ) ! , thanks so much for your time and your great effort !

Hello. Thanks for sharing your knowledge and your time doing this very useful video. Again thanks from a Brazilian student. :)

This was SO helpful...I needed to pickup on .Net Core API creation for my job and this one helped immensely to get an overview of how to do it....Please keep the videos coming in...much love and respect!!

I like how you walk through the tutorial, explaining everything in good detail. This is how tutorials should be made. Thanks for the hard work.

Great tutorial. Thank you for doing everything from scratch. In case anyone else got stuck at the Entity Framework step, I also had to run the following command to install the ef tool globally: "dotnet tool install --global dotnet-ef"

I love the way you start coding from the beginning and explain everything

This was a fantastic tutorial. So many other people don't get a good balance if when to go into detail and when not to. I felt as though you did a really good job on this. Explained relivant info and briefly mentioned the rest so we could research it for ourselves. Thank you for taking the time to make this! I found it very helpful.

Great video For .Net Core 3.0 you can either 1) Use the new webapi template 2) Use this command to setup MVC: services.AddMvc(option => option.EnableEndpointRouting = false).SetCompatibilityVersion(CompatibilityVersion.Version_3_0);

Perfect tutorial! Thoroughly explains how to create endpoints and what each method does. Thank you!

Thank you man, I really appreciate that you speak clearly, so for people that English is not part of the "normal" language, help so much that you speak simple and clear. Also the content of your video is so helpful. Have a great month ;D

Great tutorial. I had to change it a little bit when using .Net Core 3.1, but still awesome.

The only one .NetCore tutorial I found worked. Thank you very much!!! Waiting for advanced series

Most excellent. Thank you! I backed my way into this from your Microservices full course, wherein you alluded to a previous video explaining websockets and signal r, and then from that video into this one when I was running into problems with versioning stuff, being as I am a relative newbie. I had to work through a number of issues because so much has changed, but I am so very grateful for the whole experience. I learned about Postman and how to use NuGet to pick an align versions of this with versions of that, and, of course, how to do what the tutorial taught. I am much improved for your efforts and mine. Bless you, Les! Now, I am going to resume the tutorial of yours that led me here, intending to complete that one so I can get back to where I was in your Microservices tutorial. I really can't thank you enough, Les.

You are the best!!. I will keep following your tutorial and recommend same to my colleagues. Thanks for your efforts and to say it comes free, I lack words to express how I feel. Thank you Les!

Great tutorial! Please keep this "under the hood" approach when teaching technical stuff, its really good.

It was a wonderful Tutorial. Many Thanks for your time to make this Tutorial.

Thanks Les, this is a great introduction. It's a lot to take in for a new guy but it wasn't overwhelming. PS: In .Net 3 you gotta modify "AddMvc" in the Startup.cs to this: services.AddMvc(options => options.EnableEndpointRouting = false).SetCompatibilityVersion(CompatibilityVersion.Version_3_0);

Your explanation has opened my eyes to how entertainingly simple solutions can be on point. Thanks Les!

This is pretty cool and straight forward, I was looking for some asp net core tutorial and got confused by the tutorial but this one is different. Hope I can give multiple likes.

Good one mate! Just an observation... at the PUT action you should also check if the id passed in the route and the id of the object passed in the body exists... otherwise you're going to get an exception

Awesome tutorial! Even though I used MySql I managed to use another tutorial to set-up the DB and catch up with this one. Thanks a lot!

This was helpful even though I am using .net core 3.1. Just had to tweak some startup configurations. Thank you so much for sharing!

Thank you very much. This was an incredible project example. Appreciate you taking the time to teach and share the knowledge!

This is great video. Thanks for the way you explain things.

A video specifically for beginners about what it was worth indicating in the title, a few comments. To work with a real database, it is better to use IQueryable. And for the context of the database it’s better to create an asynchronous service that implements an interface for weak connectivity and inject it into the controller so the code will be cleaner the controller will not perform any checks and unnecessary movements by calling only the service and passing parameters there.

By far one of the best tutorial, truly hands on. Thank you very much

Les, you could be our leader to the promised land! Any tutorials on Asp.Net Core, Entity Framework Core, SSMS would be awesome! Awesome blog as well

awesome tutorial, all in a nut shell.

Thank you so much Les! I was so in need for someone who can teach me in such simple way. Hats off to your dedication and effort in helping us all out here. Really appreciate it.

You make this video it's very meaningful. It's still helpful, even though i'm using .net core 3.1. You should make more video with empty template. Thanks for sharing your knowledge.

Phenomenal tutorial. Thank you for taking the time to explain this in depth.

This is exactly what I was looking for! Thanks a lot I used your demo for my boothcamp project

Hi Les, amazing tutorial !!! At work, we often invoke stored procedures to supplement CRUD. So I extended your example, just a little bit, to do a "FromSql" query in the controller to get the Result-Set from a stored proc. The changes are minor, and if you are interested, I could send you my code snippets. It might help someone else out. Thanks Again !

thank you so muck for this tutorial! I have an assignment about this in college and didn't know what was going on. You made it very clear!

Nice Tutorial. Subscribed, Love from Nigeria

A bit lengthy, but captures all the aspects as promised. Thanks Les. This was an awesome tutorial for us

Thank you for your clean and clear explanations. You must do this tutorials on Udemy or other platforms your are better then many of the "trainers" there. I learn from you in one video what i have not in hours on video courses and tutorials.... Keep this great job that you do and ... expand it :)

2021 and still very informative. Of course some updates relates to ver3.0 has to be made but all is managable.

Great tutorial. Thank you for doing everything from scratch.

You should have way more subs, this is fantastic! im using this but making it asp 3.1

Excellent video, Les! Thank you for making it.

Man, you are so cool. Thank you for all of your tutorials, they are great, really helpful. Sending love from Serbia!

Thank you so much for this tutorial! I love that this is such a beginner-friendly one. But most of all, I want to thank you for doing this in a text editor. As someone who doesn't like IDEs anymore (because it does a lot of magic behind my back), looking for tutorials about .NET related things is hard because they always use Visual Studio. Like how are you going to learn Azure deployment of a Blazor web app when you just press the publish button in your IDE and poof it works... Thanks again for this, this taught me a lot. Hopefully, you make more! :)

Hello from Canada. Excellent training. Thank you.

Incredible tutorial!!! It helped me a lot. Greetings from Brazil!

Great video. It's hard to find a .Net Core tutorial using CLI. Most of the tutorial in youtube are using VS PMC. Just wanted to point out that EF Core have an Update method so you don't have to write the State Modified to do an update. Looking forward for an advanced tutorial on .Net Core from you

Thank you Les. Very nice

Wow thanks for this! I'm trying to learn .NET core and this was a great place to start! :D

Outstanding. You make it look easy, great job.

Great! It was very easy to create my first REST API using .Net Core. I have to say that my experience with .Net Core is null... :) This video is high recommended!!!

You are such a lovely teacher. I loved implementing it and the learning was so good. Thanks for such a great video. Lots of loves❤❤❤❤ from INDIA

Thank you for this great tutorial!

Very very very helpful tutorial. Thank you so much for this tutorial. :)

Great video, i've learned a lot. Doing it on Visual Studio game me a little problem with packages, but in the end everything worked like the video. Thanks.

Simply amazing, thank you for making it easy to understand!

Subscribed!!!. You are awesome to explain the concepts very clearly. Thanks Les!

Very good tutorial for REST API.

Very nice video. I understand it very easily.

There was an update to dotnet. If you're following the tut. be sure to use this command when using entity: dotnet tool install --global dotnet-ef --version 3.0.0

Thanks for your excellent tutorial.

Thank you for making time to teach us

Thanks man! Great tutorial, please keep doing. Peace.

Nice step by step tutorial on dotnet core api, please also make tutorials using dapper if possible

Hi Lee. Great tutorial .Thanks for you effort and time. You mentioned in this tutorial that you covered Json Patch Method in another link. Do you perhaps have this link? I need to patch back to MSSql dataset

Good tutorial!

wow, this is an excellent tutorial on this matter. thanks a lot!

Thanks for the awesome Lesson. Thank you.

@Les Jackson Thank you soo much for this Video , I am glad to watch this , I always wanted to learn ASP.NET Core in Linux Ubuntu , but no video was in Visual Studio Code , But your Tutorial Helped me a lot, Once again Thank You So much

Man you are awesome.. It helped me a lot. Thanks

Thanks for this!! Amazing video and explanation. It lights me a lot!

Thanks for the video, really nice and well explained. Thanks many times

None of the previous tutorials that i've seen, explain so clear and from scratch the base concepts that you need to understand to develop a big project, and for my case , this info is very important because I am new on this framework. Thanks a lot really. I have one question, what videos or info do you recommend to get after this video? My goal is to learn to build APIs on .net core with a "good" architecture and viable for the current market. Greetings from Argentina

Very clear and straight forward tutorial, well-done! Somehow [Route("api/[commands]")] didn't work so I just used a hardcoded url [Route("api/commands")] instead, and I also have to create my own appsettings.json, as it's not created automatically.

Is there a specific reason you use VS code over Visual Studio?

thank you oldman!

thanks aussie bro, this helped a lot

best dotnet tutorial

Loved your tutorial! Thank-you for all your hard work. Can you recommend any good material to understand MVC and other System Designs

Just a note for those of you using dotnet core v 3.0 instead of adding Mvc to the services, use "AddController()" and "AddRouting()" to the ConfigureServices method. Then in configure, use app.UseRouting(); and app.UseEndpoints(endpoints => { endpoints.MapControllers(); } Microsoft wants endpoint routing to be done differently.
