Just bought and now reading Professional ASP.NET MVC 1.0 by Rob Conery, Scott Hanselman, Phil Haack, Scott Guthrie. I don't often buy computer books but I read the first chapter from a PDF that is available online and was suitably impressed with it and since I am working in ASP.NET MVC knew I needed the knowledge so went ahead and got it.
It's well worth it. If you're doing any ASP.NET MVC work and you need a tutorial or reference book on the subject then this one is excellent. I like the Product Team Asides where they describe what they discovered during the development of this framework and why they took certain approaches.
Something which I'm curious about though is why would four Microsoft employees writing about Microsoft technology publish a book through Wrox Press and not through Microsoft Press?
