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.

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

Possibly your problem is that the connection string you're using is a standard SQL Server one rather than the Entity Framework one. See this answer.
