FWIW, I wrote a tutorial, ADO.Net Step by Step, about which people have said
nice things _provided_ you're working with VB (there are so many typos in
the C# code, I fear it would be more confusing than helpful -- not my fault,
but my responsibility).
The reference book I rely on and can recommend wholeheartedly is David
Sceppa's ADO.Net Core Reference. Both are from MS Press.
