Professional engineering books

On my spare time at home, I'd been reading "Professional C#" and you would think it is really for professionals. The problem is that is that it's overly verbose, for many of the different components.

How does a software engineer not know what an interface is, or what a stack/heap/dictionary is? It goes into detail with language that seems to be geared towards the 9 year old. Come on! You don't have to explain everything to make your book so thick. So there seems to be a ton of whitenoise in it compared to real information.

Next time, I'll sit through reading it a lot more before jumping into purchasing my next book. Also, I think I'll most likely stick with authors who I recognize and have read before, because it is just awful.
