I quite agree with the first reviewer with regard to why MySql (or even Oracle) appears in the title. The book can stand on a solid ground on its own without these names (say, just keeping to SQL Server database). MySql only gets a passing comment with most of this just being generic information and less to do with ADO.NET (such as how to install MySql). For consistency as well as current programming trend, I would have liked all the coding examples confined to C# rather than randomly picking between C# or VB (or both at times). Other than these rather minor comments, the book generally represents a good reference on the subject (shown in large bold letters in the title!).
