Is there a simple & extendable Data Class for ASP.NET?

Question

I've worked with a few of these in the past, but I'm looking for a good, reliable and extensible data class for ASP.NET 3.5, that I can adopt and extend for future projects.

I'm not looking for LinQ, and I don't want anything which won't be a source-code level solution.

Ideally, it also won't be heavy.

Answer 1

Your question is too vague. What do you mean by "data class"? What do you want/need it to do for you?

Are you looking for something like DataContract?

Answer 2

You might want to look at Mircrosoft's Enterprise library's Data Access Block I have found it useful and it is a building block of .netTiers. Patterns & Practices Codeplex page

Answer 3

I wish there were something similar to the DataSet/DataTable/DataRow/etc ADO data classes, but open for extension. While working with them is sometimes very hard, they make many expensive and complex tasks easy. Its a tradeoff, definitely.
