Was looking at the documentation for the AC Event System. Given the example, EventsManager.Instance.OrderPlaced += new OrderPlacedHandler(eventHandler.OrderPlaced), it appears this is a static implementation.

I'm trying to keep everything I can in the plug-in so we're not modifying the core code. What is the preferred method for us to tie in our custom event handlers so they are only added once?

The documentation says "hook these event handlers functions at application start". To me that implies customizing Application_Start() within Global.asax. That seems to defeat the purpose of a plug-in system. Is there a way to inject our event handlers via the plugin system that I'm overlooking?

For instance, is there a RegisterEvents function, or something similar, that we can tie into that only fires once?

You can inject your event handlers in the RouteProvider class of the plugin.

Following the documentation example:
Open your plugin RouteProvider class and add the following code at the end of the RegiterRoutes function.

Code:
var eventHandler = new MyEventsHandler();
EventsManager.Instance.OrderPlaced += new OrderPlacedHandler(eventHandler.OrderPlaced);
EventsManager.Instance.OrderCancelled += new OrderCancelledHandler(eventHandler.OrderCancelled);
