Yep. Have fun. Try not to lose as much hair as I have.. :/

Been there, done that. The answer: not really. Firstly, the 'event' pattern is first-class in the framework so I have to deal with it (meaning that in many cases I do not control both sides of the code). Secondly, WeakReferences only really introduce a new set of problems. Performance is one, but not as big a problem as 'what do I do if an event gets thrown to a dead object that hasn't been collected yet?'.
At the end of the day, I need to unsubscribe my events. So all that this 'managed environment' seems to have done for me has turn 'delete' into 'unbind', 'dispose', 'null'. It didn't become easier, it became harder. Meh.

Yep. I checked the IL too. I only discovered this last week. Then I started grumbling about not having an 'in' keyword..
