ASP.NET MVC 4 Code first, How add tables using Code first

Im playing currently on visual studio 2012 asp.netmvc4 with simple membership. This will generate 5 tables after running.

My problem is how do i add additional tables? I tried by creating a new model and adding a DbSet on the context class but it will throw error saying dbo.model does not exist in the database. The table is not created.

Is there a standard way of adding a model that will generate a table without running db migrations command?

I even added this Database.SetInitializer(new HWMDContextInitializer()); on application start but the error is still there.

If you want Entity Framework to drop and regenerate your database automatically whenever you change your model schema, use data migrations.

For more information refer to the documentation: http://msdn.microsoft.com/en-us/data/jj591621.aspx

Have you tried this?

protected override void OnStartup(StartupEventArgs e)
    {
        base.OnStartup(e);
        Database.SetInitializer<YourContext>(new DropCreateDatabaseIfModelChanges<YourContext>());
