[Mono-osx] [MonoMac] "Apply Protocol to Class"

[Miguel de Icaza]

Hello,

So I was looking into this, and the recommended use case for the
NSArrayController is not to set it as the delegate/data source as you
described, but instead to use Bindings (KVO/KVC) to hook up the data,
and this would require no intervention on your end for this, nor
implementing the protocols like that.
