Praise for Earlier Editions of
ASP.NET MVC in Action
This book does a good job of not only showing you what to do, it also provides
cautionary words to avoid poor practices that may lead to maintenance issues on
non-trivial applications.
—Venkat Subramanian, NoFluffJustStuff Blogs
I really enjoyed ASP.NET MVC in Action and highly recommend it for a fresh look at
the ASP.NET MVC framework.
—David Hayden, Microsoft MVP
ASP.NET MVC in Action will guide you from your first project through advanced
topics such as AJAX and deploying on suboptimal hosting environments. The writing
style is clear and concise. Diagrams and code examples are abundant. I recommend
it for anyone looking for a great resource for learning about or becoming a better user
of the ASP.NET MVC framework.
—Nathan Stott, Partner and Software Engineer, Whiteboard-IT
I’m very happy with this book. I would definitely recommend it to anyone interested
in ASP.NET MVC. Getting beyond the text that comes with the CodeCampServer is
just icing on the cake.
—Chris Stewart, CompiledMonkey.com
The authors not only did an excellent job of putting together a great practical guide
to ASP.NET MVC, they also successfully embedded some subversive ALT.NET concepts
that will make us all better developers. And at the end of the day, that is a damn fine
accomplishment!
—Bobby Johnson, AppExtremes
As my first introduction to MVC, I found this book very readable and interesting.
—Roger Wright, Engineering Manager, Aha Macav Power Service
