dbcontext - Entity Framework - OnModelCreating with Model First

Question

I have a Entity Framework model set up with text templates to generate the code. However, one of them creates the DBContext containing an OnModelCreating.

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        throw new UnintentionalCodeFirstException();
    }

How do expand on this, since a partial class with the same override does not work.

Answer 1

You cannot use OnModelCreating when using model first (EDMX). OnModelCreating is only for scenarios without using EDMX.
