Entity Framework not creating tables

I am using code first workflow. Entity framework was creating tables for my models automatically upon adding migrations. It has stopped doing so. How can I fix this issue?

Are those tables added to the dbcontext?

Let me check real quick I haven't needed to manually add them into dbcontext since my first couple tables it was reading my model changes automatically

What I mean, is DbSet<TheModel> properties If not, are they referenced in other models? If you have Foo and it references Bar, you only need a DbSet<Foo> and EF will figure out that Bar should also be a table Not the best ideal, it's better to add everything as a dbset, but it does work this way

Ah ok I understand. I forgot where dbcontext was because I have been referencing other models in models that are in dbcontext 😦 found it, ok I will add it to dbset thank you @Angius I have another issue now. When trying to reference a model in another model i am getting this error The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_dbo.Movies_dbo.Genres_GenreId". The conflict occurred in database "aspnet-web_template_001-20230102051540", table "dbo.Genres", column 'Id'.
