how to use typed DataSets in c#?

I tried to google but didn't find a decent tutorial with snippet code.

Does anyone used typed DataSets\DataTable in c# ?

Is it from .net 3.5 and above?

To answer the second parts of the question (not the "how to..." from the title, but the "does anyone..." and "is it...") - the answer would be a yes, but a yes with a pained expression on my face. For new code, I would strongly recommend looking at a class-based model; pick your poison between the many ORMs, micro-ORMs, and raw ADO.NET. DataTable itself does still have a use, in particular for processing and storing unpredictable data (where you have no idea what the schema is in advance). By the time you are talking about typed data-sets, I would suggest you obviously know enough about the type that this no longer applies, and an object-model is a very valid alternative.

It is still a supported part of the framework, and it is still in use as a technology. It has some nice features like the diff-set. However, most (if not all) of that is also available against an object-based design, with classes and properties (without the added overhead of the DataTable abstraction).

Sparingly.... Unless you need to know to maintain legacy software, learn an ORM or two, particularly in conjunction with LINQ. Some of my colleagues have them, the software I work on doesn't use them at all, on account of some big mouth developer getting his way again...

MSDN has guidance. It really hasn't changed since typed datasets were first introduced.

There are tons of videos available here: http://www.learnvisualstudio.net/series/aspdotnet_2_0_data_access_and_databinding/

And I found one more tutorial here: http://www.15seconds.com/issue/031223.htm
