Since my announcement last year that there would not be an update to my book (“Pragmatic ADO.NET”) to show the changes in ADO.NET 2.0, I have been asked what book I would recommend. I have scoured the ADO.NET 2.0 books and finally have a firm recommendation:
Pro ADO.NET 2.0, by Sahil Malik
While it is not the book I would have written, it is a very good book. It covers ADO.NET 2.0 very thoroughly and in a very readable manner. If you need an ADO.NET 2.0 book, go get this book today.
