Although I have marked my ID column with .Identity(), the generated database schema doesn't have IDENTITY set to true, which gives me problems when I'm adding records. If I manually edit the database schema (in SQL Management Studio) to have the Id column marked IDENTITY, everything works as I want it - I just can't make EF do that by itself.

This is my complete mapping:

public class EntryConfiguration : EntityConfiguration<Entry>
{
    public EntryConfiguration()
    {
        Property(e => e.Id).IsIdentity();
        Property(e => e.Amount);
        Property(e => e.Description).IsRequired();
        Property(e => e.TransactionDate);

        Relationship(e => (ICollection<Tag>)e.Tags).FromProperty(t => t.Entries);
    }
}

As I'm using EF to build and re-build the database for integration testing, I really need this to be done automatically...
