Author David Sceppa has brilliantly explained ADO.Net at length using very lucid language. Best part of the book is usage of generic .Net Provider [OLE DB .Net Provider] to explain the intricacies of the framework, and later in the appendix A, author details out usage of standard .Net providers like SQL Client .NET Data Provider and Oracle Client .Net Data Provider. Moreover the tools provided in the CD are quite useful for Adhoc query and Data Adapter Building. Both VB.Net and C# Code samples, the eBook on CD are of great help. SQL XML .Net Data provider is the highlight of the book. The book is worth more than its price.
