Why $C^{\infty}(M)$ module of sections of a vector bundle $E\rightarrow M$ is a reflexive module?

Here we are considering vector bundles with finite-dimensional fibers.

Surely this just boils down to the fact that it's true fibrewise? –  Zhen Lin Oct 30 '12 at 18:31
I have no idea.. I'm new to this area and and everything is totally a mess to me now..maybe I will read more and think over it again.. –  hxhxhx88 Oct 31 '12 at 4:37
Can you say something about the source of this fact? –  Fallen Apart May 2 at 14:09
