NET2.0 implements net3.5 features, such as extension methods, LINQ, etc.

Almost two years did not touch net, today want to do a small tool, so opened a long-lost VS2012, due to customer terminal or WinXP era, and is net2.0, and the upgrade has limitations, it must be developed in 2.0, the former common library is 3.5 write, and because 3.5 of the extension, LINQ and so very fast and convenient, so write up 2.0来 very awkward, on-line check, incredibly find a very simple way, specifically to write down:

1. Add the System.Core.dll in net3.5 directly to the 2.0 project (reference), and the "specific version" in the property is set to False

2. Using System.Linq in the code;

Happy to play it ~
