callback or event?

[David]

I need to implement in my class something to notify events to the
application.

I must focus in the performance, so maybe you can tell me if is better to
implement a event or a callback (using delegate directly)
Thanks

Assume this is VB.NET? Whether you use event keyword or directly wire your
callback via an explicit delegate, you will end up with the same IL (or
nearly so), so I am not sure either is a "better" solution.

I am personally more fond of explicitly coding delegates, but a person adept
at VB will be more used to event handling with the Event keyword. Choose
based on who will maintain.

David,

Events use callbacks so you're really talking about one and the same thing.
If you want to use events then you should implement an Event.
