As was said, the book tries to keep things simple. But at certain points it perhaps goes even too simple. Some things are covered with a few words even if one would expect a bit more details though most of this could be explained with the early version of the product. One example of this is the discussion and examples related to provider implementation for Membership and Personalization features where one might expect to get even more concrete examples, despite that the main line is to give an introduction. Luckily the most important new features are very well covered and the example I mentioned wasn't so bad but it could have been even more detailed. This is perhaps a result of the aspect that authors have now given more explanation than providing exact details.

Another thing to complain of is that there isn't so much sample code provided and samples aren't really real world oriented, but they do their job and demonstrate the new features.
