I own asp.net mvc in action as well as this book but I have to say this is much more organised in terms of flow and explanation. Small pieces of code to illustrate each concept works great for me. On contrary, asp.net mvc in action talks of a code camp app and might not be the first book you want to read since you might get lost if you are new to MVC. Nothing against asp.net mvc in action since it is a good book as well but you will grasp much more if you read this first and then dive into "in action".

I've always been a fan of Stephen Walther's [...]Unleashed book (arguably one of the most popular[...]books ever) and his latest [...]Unleashed book doesn't disappoint. As with his previous book, Stephen takes the time to walk through a lot of nice details that other books tend to skip over such as creating data repository classes and interfaces, integrating data repositories into controllers, tips and tricks that can be used during unit testing, building custom HTML helper classes, [...]using caching, adding jQuery into the mix, plus much more.

If you're interested in a book written by someone who really understands how to explain technology and who knows the [...]framework inside and out then I'd highly recommend getting this book. Stephen Walther knows his stuff and explains the technology in a way that's easy to digest. Code samples are provided in both C# and Visual Basic.
