What readers are saying about Rails for .NET Developers

Eng and Cohen, like a modern-day Lewis and Clark, have blazed a

trail that .NET developers can follow to the new frontier. If you are

a .NET developer and are considering moving to Ruby on Rails, then

this book is the place to start.

James Avery

If you’re ready to make the rewarding trip from .NET to Rails, this

book will give you the road map you need.

Mike Gunderloy

Former .NET Developer, http://afreshcup.com

This book will be a tremendous aid to anyone making the transition

from .NET to Ruby on Rails. All the major topics a new Rails developer

should become familiar with are covered in great detail.

Michael Leung

Lead Developer, Urbis.com

Jeff and Brian have done a wonderful job of explaining Ruby on Rails

to .NET developers in this book...but there’s more value here than just

learning a hot technology. Jeff and Brian show you how Ruby on Rails

can make you a better developer no matter what platform you use, as

well as how it can inﬂuence how you design and write web applica-

tions.
