Setting the Database initializer should not be done from the RunWeb persistor with code first any more

Hi Guys,
           The NO fresh install package has the Persistor property in the RunWeb class as
protected override IObjectPersistorInstaller Persistor
            // Database.DefaultConnectionFactory = new SqlCeConnectionFactory("System.Data.SqlServerCe.4.0"); //For in-memory database
            // Database.SetInitializer(new DropCreateDatabaseIfModelChanges<MyDbContext>()); //Optional behaviour for CodeFirst
            var installer = new EntityPersistorInstaller();

            // installer.UsingEdmxContext("Model").AssociateTypes(AdventureWorksTypes); // for Model/Database First
            // installer.UsingCodeFirstContext(() => new MyDbContext()).AssociateTypes(CodeFirstTypes);  //For Code First

            return installer;
However your current recommendation is to Context objects defined in the Model project
Where you would set the Database initializer.

protected override void OnModelCreating(DbModelBuilder modelBuilder)
        //Use the Naked Objects > DbInitialiser template to add an initialiser, then reference thus:
        //Database.SetInitializer(new MyDbInitialiser()); 
        Database.SetInitializer(new DropCreateDatabaseIfModelChanges<UWASDbContext>());  //Optional behaviour for CodeFirst

        //Use the Naked Objects > DbMapping template to create mapping classes & reference them thus:
        //modelBuilder.Configurations.Add(new EmployeeMapping());
        //modelBuilder.Configurations.Add(new CustomerMapping());
It looks like you should remove the commented out code in the Persistor property.
