Great tutorial, thank you! Right what I was looking for. When researching this topic (Web API) there is often a lot about interface and repository. The approach you showed is more easy to grasp for a beginner.

Yes the idea was to get people started with entity framework instead scaring them. Thanks for a lovely comment 😊

[@waqasriaz30]

A comprehensive video series. Loved your videos. There were two abruptions I faced when following your video series and can be improved: 1. The user login method wasn't created when using visual studio > add controller > scaffold new item. I presume you made it backstage and later in your uploaded videos, it suddenly appeared to viewers. Even, the scaffolding part was missing. 2. The link to your GitHub project > 'code.txt' file doesn't contain the code you showed in the videos. For the students, the video series is worth giving time. I learned a lot in such a short video series about Web API and associated tooling to professionally handle this project. The knowledge given in this series highly overrides the above abruptions being pointed.

[@CuriousDrive]

Thanks Waqas, that's an awesome feedback. I see what you are saying about the login method. I did add that behind the scenes and did not scaffold it. But visual studio wouldn't have scaffolded as it not one of the EF Core method. I hope that makes sense. And I used "code.txt" file for back up, it is not part of the tutorial. Thanks again for suggesting this tutorial to students.

[@guillermoruiz3568]

Hi, this is the first video that I see and I really liked it, you have a new subscriber. If you fix a new project, use DataBaseFirst or CodeFirst?

[@CuriousDrive]

Honestly it depends on the size of your project. If you are making a project where you have less than 10 tables and you don't really care about your data in the future then CodeFirst is a easy and fast approach. But you have lot of data now or there will be in future then I would go with DatabaseFirst approach. Because then I have freedom to switch to any other ORM framework. And you won't have to maintain your migrations. Your architecture should be independent of your framework. Always build your base first. that's how I code :)

[@Artavazd.kirakosyan]

let me ask one more question, as I understood, whenever we make a call to database, we create new instance of context, and as so, we pull of all of the data (including all of BbSetsName ) from databases to our context object. did I get correct? in other word, this approach is assumes heavy data transfer from/to database .

[@CuriousDrive]

No. EF core does not make call to the database when you create the instance of DBContext. It makes calls when you access the DBSet. And if you use LINQ to filter your collection then it creates the query with where condition. Performance was the main focus when they were designing EF core. I hope that makes sense

in asp.net core web api : if there are 10 method in one controller i want 10 method return in json formate and 10 method return in xml formate then how will do it?

[@CuriousDrive]

Hello Mithilesh, sorry for the late reply. Please check below article for producing responses in different formats docs.microsoft.com/en-us/aspnet/core/web-api/advanced/formatting?view=aspnetcore-5.0

[@Artavazd.kirakosyan]

I got a question to ask regarding to controller, here you use very simple way to connect to database to pull or add a new data (i.e. author). in other cases, many people use dependency injection where they need to go through series of settings in startup, repositories, and controller (particularly dependency injection in controller). just wondering which approach is preferable? this one (i.e. using(new connection object ... )) is obviously more simple in terms of configuring and using in controller....

[@CuriousDrive]

Artavazd, that's a great question. The reason why I did not use dependency injection in this case because it would had been difficult for beginners to understand EF Core. But if your DI concepts are clear and you know how your app should be structured to be durable then please use DI.

Is it possible for you to increase the sound and upload the files? This sound is very feeble. Video looks great.

[@CuriousDrive]

They seem to be fine for other people. You can download this video and use some online tools to increase audio gain f you'd like. I will loose view counts if I re-upload these videos, also subscribers won't like that.

[@svantepanter]

Works fine for me!

[@klsonic]

Is the web api you've created a rest api?

[@CuriousDrive]

Yes. You are correct.

Thank you for this video. It's very useful. How to set database user name and password on connection string?

[@CuriousDrive]

Server=myServerName\myInstanceName;Database=myDataBase;User Id=myUsername;Password=myPassword;

[@ReelSkilla]

Can I user mysql db for this?

[@CuriousDrive]

Jeremaine, YES. the only thing that you will need to change is the provider in that case. You can follow this article - dev.mysql.com/doc/connector-net/en/connector-net-entityframework-core-scaffold-example.html

[@samreenfarooq8274]

I had to add "TrustServerCertificate=True" in connection string as well otherwise it wasn't running

[@akshayparashar2348]

hey can u pls tell me how to update generated models from scaffolding?

[@CuriousDrive]

Hello Akshay, I am explaining that in the next episode of the series.

[@thanhatle7257]

All are good, but I think u need to talk loudly and clearly, cuz I did had my volume up to 80 to watch the video >v

[@CuriousDrive]

I know. Other people complained about that too. I did not have a good microphone and no video editing skills. The new videos are better. Thanks for watching this one :)

[@AbdulRafay-wy3ve]

anyone help me how to import giving database into my database??

[@LuigiZambetti]

Hello, could you suggest me the best book on EF Core and Web API Core? Maybe one that you have used to in the past.

[@CuriousDrive]

Hey Luigi, I personally read either from microsoft docs - docs.microsoft.com/en-us/ef/core/ or this website has very organized information about EF in general - www.entityframeworktutorial.net/what-is-entityframework.aspx I see what you are saying though, I miss reading books too. These frameworks are updated every quarter, I don't think any book will be good as it will be outdated pretty soon. microsoft docs does give you an option to download PDF on left bottom corner though. Something to read on the train ride :)

has anyone encounter this error: System.Runtime.InteropServices.SEHException: 'External component has thrown an exception.' ??

[@CuriousDrive]

What version of VS are you using and do you have .NET core installed on your machine?

[@peymanx]

@@CuriousDrive Thanks for your response, It was about 'Platform Target', I changed it from 'Any CPU' to 'x86' and it runs perfectly,.now. ❤

Could you please explain one example, How to use stored procedures in webAPI with entity framework Thanks, Raghavendra

[@CuriousDrive]

Hello Raghavendra, I have plans to make a video series on ASP.NET Web API for .NET 5 framework. I am going to cover how you can call stored procedure in that series but meanwhile you can take a look at this article. I hope this helps. www.entityframeworktutorial.net/efcore/working-with-stored-procedure-in-ef-core.aspx
