CSLA->NH generator

[sanyo]

Hello,

I am looking for a tool to generate two layers at once:
DAL: in nHibernate
BO: in CSLA

So that server side DataPortal would use nHibernate for CRUD

Please let me know why CSLA often stands in generators as a
replacement or alternative for nHibernate or other ORMs while being a
universal business layer rather than a DAL oriented thing?

Thank you,
Alexander
