For an upcoming project C# code needs to be written around a legacy Oracle database. It will be very data centric, because most of the code will deal with data manipulation -- there are almost no business rules. So I decided against a full blown ORM and opted for an Active Record approach. I come across two options: SubSonic and Castle ...
I'm trying to have a simple one to many relationship/hierarchy using NHibernate.

If I were in an immutable Functional mood, I might do something copy-construtor-like, like this: from widget in widgets select new widget { legs = widget.legs + 1, arms = widget.arms } Sadly, I'm doing this on a mutable NHibernate entity object and I have to modify the origi...
