I am a new C# learner. I have two questions here. Can anyone give me the answer please.

1. What are the relative advantages and disadvantages of Windows versus Forms authentication for web applications in ASP.NET?

2. What are the advantages and disadvantages of modelling data within a DataSet as opposed to custom objects?

I assume you mean "Beginning Visual C#". Try looking about 4" above your nose, on the screen when viewing this message at http://p2p.wrox.com. There is a button labeled 'Download Code'. Read EVERYTHING in the first six paragraphs and THEN look in the table following them. You will find what you are looking for.
