Excellent intro to repository patten with EF Core!

This is one of the easiest to understand videos I've watched on c#

[jayeshsingh]

What you said about not worrying too much about whether to use the repository pattern or not was really helpful!

[konstantinosantoniou]

Simply said and nicely presented. Good work!

[sampathchaganty]

How did you get intellisense so show the namespaces when you typed "IBookRepository" in 6:45?

[Cyrdian]

Your controllers and repositories are all directly dependent upon EF. Now try testing without a database; you need to rewrite all your repositories as test repositories. Also what you wrote is a data provider for EF. Repositories should be agnostic of persistence technology and may access various data providers. This is why repositories should be implemented in the business layers and not the DAL. Repositories should answer business queries, not simply wrap a specific ORM.

I would have included transactions as well, even for a getting started.

Quick question about Clean Architecture. If my application doesn't share info with other apps - is there still a need for the Domain layer?

[zedshockblade]

If youre gonna add Entity framework validation property such as minLength/maxLength, [required] etc. . Should we put it in the domain model/entity or putting it only in DTO is fine?

[solracepilif]

I have a question: makes sense (and we must do that) the construtor of the repository receives as a parameter an interface of the AppDbContext instead oh the concrete class? Or this wouldn't work? I'm asking it regarding to keep the code loosely coupled and all the good and recommended practices! Thanks, greetings from Portugal.
