Right. So maybe "T4 Templates" is a great thing to have on your CV, especially if you know and can discuss how to leverage that towards EF, L2SQL, datasets, POCO without necessarily having expertise creating those from scratch or using T3 previously... ;-)
"... 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
