I toyed with the idea of writing a really long and detailed review about the content of this book (like so many you see on Amazon), but in a nutshell, this book is a masterpiece, it's what all technical books should aspire to be, comprehensive, thorough, mercifully free of unnecessary flab, and deeply intelligent in its choice of concise and ingenious examples.
It left me with the feeling that I'd been hit by a truck with the word 'clarity' emblazoned on the side.
you won't be a .Net guru afterwards because .Net is Massive!
but...
it is in my view the best 'foundation' book of any kind I've ever had the pleasure to read, read it and then read Balena, Esposito et al, but I can't emphasize enough read this first, it is hearteningly and informatively brilliant. You WILL understand Visual Basic .net after reading it, after that go on to books that exploit specific namespaces like ADO.net, ASP.net, winforms, XML web services etc.. this book is not about any of that it's about the compiler, assemblies , types and the framework, the plumbing! this is anatomy class, surgery should come later, and as these things go, it's 'the business'!
It just goes to show that there are still people in this world who really do care about what they put their name to.
'****New Addition (10 months on, I've read it again)
Upon re-reading the book I was struck but how it was even more useful 2nd time round, but also particularly by how economical and highly informative the comments inside the code are. They are magnificent. I've found it very useful when the author is illustrating a particular point, to show for example, the return value of a method call as a comment to the right. When the main point of the example is 'watch out, this does something you don't expect' the code becomes complete, you can understand it without having to run it. I do think however that you understand code much better if you do run it. The point I'm making is that writing great and very succint comments is an art, and one I think the authors have completely mastered. You can read the book in transit and still make sense of all the examples.
