I can recall a considerable length of time where you thought otherwiseCan you? OK, I'll emphasize part of my sentence:
"The irony is that the typed dataset *was* the best way to do it
in NET IMHO."
Not "the best way, period," not good enough to persuade me to move and not true in NET anymore if POCO stacks up in the EF- though I'm seeing a few issues that suggest it may not be as efficient as the nHibernate version...
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
