Cant tell what I'm doing wrong

I've rewatched videos and i can't figure out what I'm missing in my code.

Configuration.cs 
using System.Data.Entity.Migrations;

namespace Treehouse.CodeChallenges
{
    public class Configuration : DbMigrationsConfiguration<Context>
    {
        public Configuration()
        {
            AutomaticMigrationsEnabled = false;
        }
#if DEBUG
        protected override void Seed(Context context)
        {
            context.Students.AddOrUpdate(
                s => s.Id,
                new Student() { Id = 1, FirstName = "John", LastName = "Smith" },
                new Student() { Id = 2, FirstName = "Sally", LastName = "Jones" }
            );
            #endif
        }
    }
}

You've got the right idea, but the preprocessor directives are placed here at different nesting levels. They should both be inside the "Seed" method definition, to control the compilation of the call to "AddOrUpdate".
