NHibernate POID Generators
NHibernate supports several POID (Persistent Object ID) Generators, including: Identity, Guid, Guid.Comb, and HiLo.
You can find a good explanation here, about the various strategies.
Avoiding Identity and going with Guid.Comb or HiLo is a good practice, but there's a slight problem when your Database is SQL Azure...
