Flow of the "story" of the book is excellent. Reader has easy task to learn the relevant things in seamless and well-laid way. Lots of opinions and insights are provided with good reasoning which is important for a developer struggling with design and architecture decisions. Author is realistic about the subject and therefore doesn't fall to write with marketing in mind.

The book covers the CLR in such detail that I haven't seen for a long time. Therefore it's easy to admit that I learnt a lot while it could be said I posses fairly advanced skills in .NET.
