Windows Workflow Foundation is a groundbreaking addition to the core of the .NET Framework that allows you to orchestrate human and system interactions as a series of workflows that can be easily mapped, analyzed, adjusted, and implemented. As business problems become more complex, the need for a workflow-based solution has never been more evident. WF provides a simple and consistent way to model and implement complex solutions. As a developer, you focus on developing the business logic for individual workflow tasks. The runtime handles the execution of those tasks after they have been composed into a workflow. Pro WF: Windows Workflow in .NET 3.5 provides you with the skills you need to incorporate WF into your applications. This book gets you up to speed with Windows Workflow Foundation quickly and comprehensively. The practical aspects of using WF are covered in a lively tutorial style with each workflow concept illustrated in C#. You'll find detailed coverage of how to customize your workflows and access them in a variety of ways and situations so you can maximize the advantages of this technology. Pro WF: Windows Workflow in .NET 3.5 is written by an experienced Windows and .NET developer. Rather than simply duplicating the available references on the subject, author Bruce Bukovics leads you through a series of practical WF topics that enable you to gain immediate experience and learn how to use the technology as you progress through the book.

Bruce Bukovics has been a working developer for over 25 years. During this time, he has designed and developed applications in such widely varying areas as banking, corporate finance, credit card processing, payroll processing, and retail automation. He has firsthand developer experience with C, C++, Delphi, VB, C#, and Java, and he rode the waves of technology as they drifted from mainframe to client/server to n-Tier, from COM to COM+, and from Web Services to .NET Remoting and beyond. He considers himself a pragmatic programmer. He doesn't stand on formality and doesn't do things just because they have always been done that way. He's willing to look at alternate or unorthodox solutions to a problem if that's what it takes. He is employed at Radiant Systems, Inc., in Alpharetta, Georgia, as a lead developer and architect in the centralized development group.
