“Framework Design Guidelines is one of those rare books that can be read at different reading levels and can be useful to different kinds of developers. Regardless of whether you want to design an effective object model, improve your understanding of the .NET Framework, borrow from the experience of software gurus, stay clear of the most common programming mistakes, or just get an idea of the huge effort that led to the .NET initiative, this book is a must-read.”
—Francesco Balena, The VB Migration Partner Team (www.vbmigration.com), Code Architect, Author, and Microsoft Regional Director, Italy
“Frameworks are valuable but notoriously difficult to construct: your every decision must be geared toward making them easy to be used correctly and difficult to be used incorrectly. This book takes you through a progression of recommendations that will eliminate many of those downstream ‘I wish I’d known that earlier’ moments. I wish I’d read it earlier.”
—Paul Besly, Principal Technologist, QA
“Not since Brooks’ The Mythical Man Month has the major software maker of its time produced a book so full of relevant advice for the modern software developer. This book has a permanent place on my bookshelf and I consult it frequently.”
—George Byrkit, Senior Software Engineer, Genomic Solutions
“Updated for the new language features of the .NET Framework 3.0 and 3.5, this book continues to be the definitive resource for .NET developers and architects who are designing class library frameworks. Some of the existing guidelines have been expanded with new annotations and more detail, and new guidance covering such features as extension methods and nullable types has also been included. The guidance will help any developer write clearer and more understandable code, while the annotations provide invaluable insight into some of the design decisions that made the .NET Framework what it is today.”
—Scott Dorman, Microsoft MVP and President, Tampa Bay International Association of Software Architects
“Filled with information useful to developers and architects of all levels, this book provides practical guidelines and expert background information to get behind the rules. Framework Design Guidelines takes the already published guidelines to a higher level, and it is needed to write applications that integrate well in the .NET area.”
—Cristof Falk, Software Engineer
“This book is an absolute must read for all .NET developers. It gives clear ‘do’ and ‘don’t’ guidance on how to design class libraries for .NET. It also offers insight into the design and creation of .NET that really helps developers understand the reasons why things are the way they are. This information will aid developers designing their own class libraries and will also allow them to take advantage of the .NET class library more effectively.”
—Jeffrey Richter, Author/Trainer/Consultant, Wintellect
“The second edition of Framework Design Guidelines gives you new, important insight into designing your own class libraries: Abrams and Cwalina frankly discuss the challenges of adding new features to shipping versions of their products with minimal impact on existing code. You’ll find great examples of how to create version N+1 of your software by learning how the .NET class library team
created versions 2.0, 3.0, and 3.5 of the .NET library. They were able to add generics, WCF, WPF, WF, and LINQ with minimal impact on the existing APIs, even providing capabilities for customers wanting to use only some of the new features, while still maintaining compatibility with the original library.”
—Bill Wagner, Founder and Consultant, SRT Solutions, author of Effective C# and More Effective C#
“This book is a must read for all architects and software developers thinking about frameworks. The book offers insight into some driving factors behind the design of the .NET Framework. It should be considered mandatory reading for anybody tasked with creating application frameworks.”
—Peter Winkler, Sr. Software Engineer, Balance Technology Inc.
“An instant classic.”
—From the Foreword by Miguel de Icaza
