Can anyone point me to a good example of IExtension in C#? I have written a simple event listener, but I don't seem to be hooking it up quite right. I want the listener to be on whenever ArcMap is on, so no interaction from the user is required to start the tool I will be writing - well, no action other than making a feature selection with the select tool. I am listening for the "OnSelectionChanged()" event.
I have found plenty of examples of an event listener class, so I am fairly confident in that part of my code. The difficulty seems to be in hooking it to the application.
Also, probably a more basic question - is this the right approach to inherit from IExtension for an event listener, or should I be inheriting from BaseTool and going at it from that direction (or something else entirely)?
Thanks very much for any input on this!
