Could you please explain what exactly COUNT is supposed to do?

Is there a reason you need this "Notify" mechanism, instead of just using a ConcurrentQueue?

Why on earth is this is being downvoted or closevoted? The only thing I can imagine is that people can't think of anything to say about it, and therefore assume there must be something wrong with the question. I'm sure if there were three or four glaring errors we'd have an answer and everyone would be happy.

@Jump3r It's possible the confusion was between the terms "TDD" and "Unit testing". These are related concepts but not synonymous

Based on that feedback, you dodged a bullet by not getting that position

@JimboJones In my opinion the best way to improve your coding knowledge is to first do what you did- implement it yourself- then go look at the library and see why theirs is (inevitably) much better :)
