Michael C. Feathers
The average book on Agile software development describes a fairyland of greenfield projects, with wall-to-wall tests that run after every few edits, and clean & simple source code.
The average software project, in our industry, was written under some aspect of code-and-fix, and without automated unit tests. And we can't just throw this code away; it represents a significant effort debugging and maintaining. It contains many latent requirements decisions. Just as Agile processes are incremental, Agile adoption must be incremental too. No more throwing away code just because it looked at us funny.
Mike begins his book with a very diplomatic definition of "Legacy". I'l skip ahead to the undiplomatic version: Legacy code is code without unit tests.
Before cleaning that code up, and before adding new features and removing bugs, such code must be de-legacified. It needs unit tests.
To add unit tests, you must change the code. To change the code, you need unit tests to show how safe your change was.
The core of the book is a cookbook of recipes to conduct various careful attacks. Each presents a particular problem, and a relatively safe way to migrate the code towards tests.
Code undergoing this migration will begin to experience the benefits of unit tests, and these benefits will incrementally make new tests easier to write. These efforts will make aspects of a legacy codebase easy to change.
It's an unfortunate commentary on the state of our programming industry how much we need this book.

Do you want to create .NET applications that provide high performance and scalability? Do you want to employ object–oriented programming techniques in a distributed environment? Do you want to maximize the reuse and maintainability of your code? Then this book is for you. In Rockford Lhotka's Expert C# 2008 Business Objects, you'll learn how to use advanced .NET Framework capabilities alongside object-oriented design and programming to create scalable, maintainable object–oriented applications. Better still, this book includes Component-based Scalable Logical Architecture (CSLA) .NET 3.6, a widely-used framework on which you can base your application development. By using the concepts and framework in the book, you can focus more on your business issues and less on technology. Using VS 2008 and C# 3.0, Rockford Lhotka shows you how CSLA .NET 3.6 allows great flexibility in object persistence, so business objects can use virtually any data sources available. The CSLA framework supports 1–, 2– and n–tier models through the concept of mobile objects. This provides the flexibility to optimize performance, scalability, security, and fault tolerance with no changes to code in the UI or business objects. Business objects based on CSLA.NET 3.6 automatically gain many advanced features that simplify the creation of Windows forms, web forms, WPF, WCF, WF, and web services interfaces, and LINQ.
ASP.NET 2.0 Programming: Problem Design Solution is aimed at describing, designing, and implementing a site much like the ones you’re probably working on or will be soon, while taking the opportunity to introduce and explain many of the new features that the new great ASP.NET 2.0 framework offers. Difficult problems are addressed head-on so you'll be ready for most of the problems you’ll typically face when writing a modern website, and have one or more solutions ready for them. Unlike many other ASP.NET books that show examples for individual pages or features, the example in this book is an integrated end-to-end site (written in C#). The entire book and site has been written specifically for ASP.NET 2.0, to use the ASP.NET 2.0 features wherever they make sense. The end-result is a website which features a layout with user-selectable themes, a membership system, a content management system for publishing and syndicating articles and photos, polls, mailing lists, forums, an e-commerce store with support for real-time credit card processing, homepage personalization, and localization. The book leads the reader through development of a site with: Account registration, personalization and theming News and events, organized into categories Opinion polls Newsletter Forums E-commerce store with shopping cart and order management Localization Administration of a site will be covered including: Full online back-end administrative section, to manage practically all data from an intuitive user interface Site deployment In building these site features, you'll learn these new ASP.NET 2.0 features: Master pages Theming Personalization & Web parts Membership & Profile modules Personalization The new server-side UI controls such as GridView, DetailsView, FormView, Wizard, MultiView, the new xxxDataSource and navigation controls, among others. The new compilation mode and deployment modes The new framework for instrumenting the site, as well as handling & logging exceptions The new ADO.NET 2.0 features (e.g. caching with database dependency) The new classes for easy distributed transactions Management This book is also available as part of the 5-book ASP.NET 2.0 Wrox Box (ISBN: 0-470-11757-5). This 5-book set includes: Professional ASP.NET 2.0 Special Edition (ISBN: 0-470-04178-1) ASP.NET 2.0 Website Programming: Problem - Design - Solution (ISBN: 0764584642 ) Professional ASP.NET 2.0 Security, Membership, and Role Management (ISBN: 0764596985) Professional ASP.NET 2.0 Server Control and Component Development (ISBN: 0471793507) ASP.NET 2.0 MVP Hacks and Tips (ISBN: 0764597663) CD-ROM with more than 1000 pages of bonus chapters from 15 other .NET 2.0 and SQL Server(TM) 2005 Wrox books DVD with 180-day trial version of Microsoft(r) Visual Studio(r) 2005 Professional Edition
