A good blog entry by Oren (Ayende) about Nullable types and how NHibernate handles them. I am starting to use NHibernate and will be sharing these jems as I find them. This is also a way for me to centralize them. =)
jlockwood: You may want to look at the ILS code. I did a couple of custom nullables for PhoneNumber and Address value objects (if I rember right). I think I also boxed a couple of primitives. I’ve used the nullables library before, but you end up using nullable fields on your classes from the library. I didn’t want to couple domain code with an exernternal library.
jmeridth: Thanks Josh, I’ll check that out.
