EventExtensions

Extension methods for cancellable event operations

There is actually no way to discover an event name in c# at the time of raising the event. It is possible to get the event name from the handler that is being executed based on the event being raised, however that is not what we want in this case. We need to find the event name before it is being raised - you would think that it's possible with reflection or anything but that is not the case, the delegate that defines an event has no info attached to it, it is literally just an event. So what this does is take the sender and event args objects, looks up all public/static events on the sender that have a generic event handler with generic arguments (but only) one, then we match the type of event arguments with the ones being passed in. As it turns out, in our services this will work for the majority of our events! In some cases it may not work and we'll have to supply a string but hopefully this saves a bit of magic strings. We can also write tests to validate these are all working correctly for all services.

SupersedeEventAttribute

This is used to know if the event arg attributed should supersede another event arg type when tracking events for the same entity. If one event args supersedes another then the event args that have been superseded will mean that the event will not be dispatched or the args will be filtered to exclude the entity.
