asp.net 2.0 xml

Below web service codes are working fine. But I forgot I can only use .net framework 2.0.
And if I take out using System.xml.linq the code will break because it uses Xelement and Xdocument, and etc.

Unfortuneately, I have to stay in framework 2.0 and anyone knows how to modify below codes working with .net framework 2.0?

Thanks

Major rewriting to remove anything that depends on a newer framework OR really ask why you have to use such an old framework.
