We've hit a milestone. We have four chapters available in the early access program (MEAP). You can see the cover of the book to the right.
My co-authors are Dave Verwer, a Rails guru, and Ben Scheirman, a .Net guru. Our goal is to have this book available with the release of the ASP.NET MVC Framework from Microsoft. This book is not a typical ASP.NET book, and we aren't covering basic or entry-level topics. This book is for folks who already understand the ins and outs of ASP.NET and want to dig into the ASP.NET MVC Framework and program in a more maintainable and testable way.
We focus heavily on loose coupling, Inversion of Control, separation of concerns, unit testing, automated builds and deployments, and extensibility. There is a very strong architecture focus to this book.
You can get the first four chapters here. See Ben's commentary here. Also, to comment on the book, give suggestions or volunteer to be a reviewer, go to the book's online forum.
