How did you create the StudentCourse table without the primary key?

[@ASPNETMVCCORE]

you can declare composite key in DataContext class

[@fejdraus]

Did like you got an error The entity type 'StudentCourse' requires a primary key to be defined.

[@fejdraus]

And how to do it that would work when using two databases? The first table is from the AuthDbContext database, and the second is the DataDbContext. A composite key in the DataDbContext. When migrating AuthDbContext produces an error The entity type 'StudentCourse' requires a primary key to be defined.
