Entity Framework Core Part 7 - Models vs Entities

Data structures in the database aren't always useful for end-users. Here's how we can reconcile the differences, and optimize our eager loading to boot.

There's still lots more to EF Core. Let me know what you want to see.

Latest version of EF by default recognises that you have renamed the column and the migration produced calls the RenameColumn method. But great to know that it didn't used to be like this. Keep the videos coming 👍

I am getting clear picture of ef core. Thank you for sharing you knowledge with us

[sakshock]

This is the best EF video ive ever watched ! Thank you 💯

[slikmargor]

Great work. I haven't seen many as detailed and providing a such thorough information about technology for beginners videos as that one. I found it really interesting. Keep it up!

I have found my new role model!
Really appreciating your explanations.

Thanks for all of your videos...you are teaching step by step, helps me better understand logic and how things work...to let you know, I would like to see how to create model implementing SelectListItem, Searchbox, and some additional features that website can offer to user and the way new data is generated by user into existing columns...sort of speak, the opposite way :)

Awesome tutorial, and great appreciation to you guys producing the amazing video！

Hi, in Author class you use virtual ICollection<Book> Books property. But previously you told that virtual keyword adds onlt overheads for eager loading. Or I've missed something?

What happens when you have another shape of the model class that is maybe more concise or something. like say you have a second version called BookModel2 that is used by a specific view where is all of this mapping logic stored?

[cooperx]

Thanks you!
What about DTOs ?
Can you use it in place of mvc model then use mvvm for view model ?

Use the auto mapper to map the entities to the dtos for mvc ?

[slikmargor]

Does the extension method have to return an Iqueryable? Does it have better performance than an Icollection?

[nick]

Thank you for this series. I would love a full C# web API tutorial but I know that's probably a big ask!

[z_prospective]

I have a question.. In what layer of the application would you put this BookModel class?

[hungnguyenviet]

In .NET 7, when rename the column, we don't loss any data in this column without changing the code in Migrations folder

Great video, is there anywhere where i can learn more about that static extension method? IQueryable<Model> ?
I would like to get a better idea of how using (this IQueryable<Book>) in this method extends the IQueryable<Book> object.
And if in this case shouldn't this be an extension to Book, or even IQueryable rather than on bookmodel? this function cannot be applied to a BookModel, right?
Thanks

Thanks a lot for a good and understandable video! 👌
