Hi, I'm using NHibernate with my ASP.Net MVC application. I'm writing some extensions (plugins) for my application. And I'm loading those plugin dynamically (from different assemblies). In my base application I have many entities and mappings defined (User, Group, etc...)

I need to create new entities in my extensions, so i.e. I'm creating News module, so I need to create News mapping. In database News table has a foreign key to User table. Is there any way I can modify my User mapping, so it will have:

HasMany(x => x.Courses)
  .KeyColumn("GroupId")
  .Inverse();

Or the only way to do it is to change code in my User class and recompile project ?

I'm not NHibernate advanced user, so any help will be appreciated. TIA.
