What is new in .Net framework 3.5? [closed]

Question

I try to keep it very simple. All I have seen in .Net 3.5fx is language upgrades i.e C# 3.0, VB.Net 9, still core CLR is based 2.0fx. I really did not find any new features (LINQ is again language feature).

Is .Net framewors 3.5 just like fixed version of .Net 3.0 framework ?

I really failed to find some thing new in core framework :(
