Query: Brought me up to speed in .NET in one Night

I agree with the previous reviewer, in that CodeNotes is a great concept.. I was able to read through this 200 page book in a night and have a very good understanding about .NET the next morning at work... Kudos to RandomHouse for such a novel concept..I disagree with the previous reviewer, in that I found the book well written and breeze to get through and understand.
