问题
I have 2 entities Users and Colors. One user may be associated with multiple colors, and one color may be associated with multiple users. I use FluentNHibernate autopersistence model to generate the database. Now I have to add to the generated table UserToColor(UserId,ColorId) also an extra field 'CreatedOn', how can I accomplish and is this accomplishable with fluent-nhibernate?

NHibernate doesn't support this. The best workaround is to create an extra class as a link table, and have a many to one relationship to it from each of your existing classes.
