  • Hi Ayrat_net,

    Welcome to the MSDN forum.

    Could you please share the code snippet about creating elements and saving changes?

    I think the DbSet<User> in class repository_abstractt<T> and class user_repository are not required, because there is the DbSet<User> in class peotri_entities.

    Good day.
