If you had a mapping file it would have been:

In your example:
[NHibernate.Mapping.Attributes.OneToMany(Class = "DemoHibernate.DataCard.Card, DemoHibernate.DataUser.User")]
is probably wrong. Class element should be "MyAssembly.MyClass, MyAssembly", and that's for 1 class - Card in your case, I guess
