I used LINQ to XML. Since it is untyped, I feel it is less safe and a bit ugly - well, easy for sure. Between DOM and LINQ to XML, I absolutely prefer LINQ - DOM is dumb, esepcailly the traditional DOM that's not integrated with xpath etc.

I am interested in LINQ to XSD as it is typed. I read about it, and saw some alpha implementation. But I am not sure whether it is a part of .Net 3.5; also whether it is integrated in VS2008 - in the sense whether it generates required types based on XSD.

looks like it is still just in alpha stage, and the last alpha version was released almost exactly one year ago Feb 20th, 2008.

No update since then.

Downloaded and tried it, nice! However I doubt whether Microsoft still want to continue with it - for past one year, there is no update at all.
