Hi, guys,

First, yes, there are a number of changes/enhancements in ADO.NET 2.0, both for server-side as well as client-side data handling.

Second, yes, Mike mentioned that I'd written an article on improvements in ADO.NET 2.0. Actually, I wrote one full one one, and in another, I devoted some space it to.

http://www.code-magazine.com/Article.aspx?quickid=0607061 (tips 1 through 6)

Most of these articles have been received well (except for a certain anonymous on-line graffiti artist who enjoys posting a '1' every week)

If you want to go book shopping, this one is the best that I've seen...

http://www.amazon.com/Programming-Microsoft-ADO-NET-Core-Reference/dp/073562206X/ref=pd_bbs_sr_1/002-5545967-8128012?ie=UTF8&s=books&qid=1174763395&sr=1-1

(though you may want to get that one on Amazon and save up to 25 dollars)

Third, at the risk of self-promotion, my reproting book has a few chapters on data handling with ADO.NET as part of a demo business application (as well as few chapters on stored procs, a few chapters on reporting, etc.) You can get it here:

Hope that helps...
