One can specify an event as either the raw event:

__event System::EventHandler * OnSomethingChanged;

or as a series of add_,remove_, and raise_ methods:

__event virtual void remove_OnSomethingChanged(System::EventHandler *);
__event virtual void add_OnSomethingChanged(System::EventHandler *);
__event virtual void raise_OnSomethingChanged(System::Object,
*System::EventHandler *);

In the latter case, when creating an attribute for the event, ie.
[System::ComponentModel::DescriptionAttribute("Something Changed")] , is it
sufficient to specify it before any one of the __event member functions, or must
one repeat the attribute for all ?

In the case of properties, applying to any of the get_ or set_ works, so I
guess the same should hold true for events as well.

Yes, I know.

I hope so but I was hoping someone knew for sure. Maybe no one has ever used an
attribute with the extended form of specifying events. I will assume I only need
the attribute on one of the three event methods.
