[Mono-osx] CoreWlan Framework binding problem

[Ashok Gelal]

Awesome! That's seems to work. But can you please explain why I need to call
the following:

dlopen("/System/Library/Frameworks/CoreWLAN.framework/CoreWLAN", 0);

Thanks again. When I get some free time, I will rewrite the CoreWlan sample
and will ask someone on git to pull it.
