Question

I thought I read somewhere that ordering your using statements and getting rid of unused ones had some kind of performance benefit…but I can’t seem to find any evidence or resources to support that…is there any truth to this?

Answer 1

From the msdn,

using-namespace-directives in the
same compilation unit or namespace
body do not affect each other and can
be written in any order.
