Thank you so much! Well explained even for a Brazilian guy like me, who has English as a secondary language.

One of the best videos explaining this! I’m using it to help build an iOS PassKit web service. The many to many requirement of the Device and Pass seem to map nicely to Author/Book. Thanks!

Glad to hear that. Fortunately, starting EF5 everything is easier as many to many relationships are also created by convention.

Hello Sir, I have followed your tutorial and configured the many to many relationship via the Model Builder. Now I have a problem, how can I perform the CRUD queries in C#? I get an error in the intellisense saying that I cannot convert from a class model to a class join model (for example, cannot convert from Movie to MovieWatchList). Do you have tutorials covering this? Please I need help.

how to query the table book and author ?

Am I missing something? Is this how this was done before? Anyhow, nowadays just put ICollection on both classes and entity fc will handle everything else

Yes, things have changed in EF 5 (EF Core 5). To be honest, it's a total mess with different EF versions. For instance on EF for .NET Framework many-to-many relationships are configured by convention (as you said) for quite a few years. However, in EF Core this was never possible and you would need an object for the joining table and configure the relationships manually. In EF Core as part of .NET 5 many-to-many relationships by convention was one of the most expected features. Together with the DbContextFactory useful for Blazor Apps and deskop apps (yes you can create .NET COre WPF apps)/

Thanl your for the video. But I still have one question. How to update. Can you explain to me how to with update many-to-many relatinship tables?

Can this very same approach be used to define triple many to many to many relationships?

Not sure exactly what you mean, but I guess the answer is yes. An entity can be involved in several many-to-many relationship at the same time.

@@Codewrinkles what I mean is the following, for example, in a shopping app there is an Order entity, which can contain many Products (which consists of 1 product), Bundle (which consists of multiple products, but is coded as a separate entity and an order can contain many bundles in it), and let's say an entity named DiscountCode contains discount codes the user can use to get discount for an order (can use multiple codes per order), making the Order entity result of a many to many to many relationship. What I mean is, can this technique be used to create such entities? Sorry if the example mentioned is not the best, I just thought of it on the fly...
