Thank you so much! I would really appreciate an addition video showing how to add a new article with tags through a form in a razor component. Thanks!!

Hi Alexander! Do you need to specify the many-to-many relationship in your OnModelCreating? Doesnt EF do it by it self, from have you have specified the classes?

[sereyvathanakkhorn]

I notice this implementation will give you a cyclic reference between the Articles and the Tags. For instance, Article.Tags has Tag.Articles and wise versa. How would go about solving the problem?

I’ve got a situation similar to this, but I have a user with a list of activities, but each of those activities contains a list of users that have that activity because of the many to many relationship and link table. Can’t figure out for the life of me how to remove that link

You didn't show how it's mapped actually, like how do I get ids of an entity and map it

[adhikarpatil]

can you provide an insert example as well?

[yohanespradono]

what if we have additional column on the join table? such as "AddedAt" for example

Hello, greetings from Bulgaria. Thank you for taking time to make and present those nice tutorials.

Please, do not get me wrong. I am learning EF as of now. Please, tell me, am I correct to think that what you did in the OnModelCreating (i.e. wth the help of fluentAPI) is redundant ? I think EF would create exactly the same result having just the two navigational properties of ICollection type in both Articles and Tags !!??
I am just checking how well my education goes.

Hi! I think it's better to create this ArticleTags table manually instead of give a chance to create by EF. Because when we need to use little more difficult Linq query it starts to be annoying to write difficult Linq queries for simple logic.

This tells you how to set up many to many relationships but doesn't tell anyone how to "handle" many to many relationships. Please think more carefully when you set the video title.
