In his blog, Tom Hollander highlights some "bloody cool Enterprise Library v2 Extensions".
Whilst mostly related to the configuration of EntLib (but including a package that integrates the config tool with VS2005), one of the comments provides a link to a Data Teir Generator for EntLib.
I think that this could be a really simple way of getting started with the EntLib - bringing it closer to the data teir functionality of Castle ActiveRecord (and its associated generator) or IdeaBlade DevForce.
YET ANOTHER toolkit to evaluate! *sigh*
