Hi Munesh,
Thank for your reply!
I agree with your post. Its for difference between .net framework4.0 and 4.5.
But my question is what are the new features in C#4.0 and C#4.5 langauge specifically not from all .net framework (which include asp.net etc., )?

Thanks for your Reply !
As per your comments( Links which you provided), I got to know we have C# 4.0 and C#5.0.
And we don't have any specific feature related to C#4.5(Which was not comes underC# 4.0 and C#5.0 features).
Please correct me if my understanding is wrong.
