Release Date: 2006-10-05
In Essential Windows Workflow Foundation, two WF lead architects–Dharma Shukla and Bob Schmidt–offer an under-the-hood look at the technology, explaining the why and not just the how of WF’s key concepts and architecture. Serious WF developers seeking details about how to effectively utilize and extend the framework by writing activities will find cogent explanations and answers here. With simple and illustrative examples, the authors demonstrate exactly how to leverage WF’s extensible programming model to craft domain-specific programs. Drawing on their unique vantage point in designing and developing WF, Shukla and Schmidt deliver authoritative coverage of The core concepts and ideas that form the heart of WF’s programming model The execution model for activities, with details of the activity automaton, bookmarking, scheduling, and the threading model of the WF runtime Advanced execution concepts, including activity execution contexts, transactions, persistence points, passivation, fault handling, cancellation, compensation, and synchronization Hosting the WF runtime in applications The activity component model, with details of validation, compilation, serialization, and visualization Databinding, XAML, dependency properties, and WF program metadata Declarative conditions and rules, activity designers, and designer hosting Custom control flow patterns ranging from simple sequencing and iteration to more complex graphs and state machines Dynamic editing of running WF program instances Essential Windows Workflow Foundation is the definitive resource for developers seeking an in-depth understanding of this novel technology.
Programming Windows Workflow Foundation

"A C# developer's book and eBook guide to the features and programming interfaces of Windows Workflow Foundation Add event-driven workflow capabilities to your .NET applications. Highlights the libraries, services and internals programmers need to know Builds a practical "bug reporting" workflow solution example app In Detail Windows Workflow Foundation (WF) is a technology for defining, executing, and managing workflows. It is part of the .NET Framework 3.0 and will be available natively in the Windows Vista operating system. Windows Workflow Foundation might be the most significant piece of middleware to arrive on the Windows platform since COM+ and the Distributed Transaction Coordinator. The difference is, not every application needs a distributed transaction, but nearly every application does have a workflow encoded inside it. In this book, K Scott Allen, author of renowned .NET articles at www.odetocode.com, provides you with all the information needed to develop successful products with Windows Workflow. From the basics of how Windows Workflow can solve the difficult problems inherent in workflow solutions, through authoring workflows in code, learning about the base activity library in Windows Workflow and the different types of workflow provided, and on to building event-driven workflows using state machines, workflow communications, and finally rules and conditions in Windows Workflow, this book will give you the in-depth information you need. Throughout the book, an example "bug reporting" workflow system is developed, showcasing the technology and techniques used. A fast-paced and practical developer's road map to working with Windows WF, from compilation to the base activity library to runtime services."

A fast-paced and practical developer's road map to working with Windows WF, from compilation to the base activity library to runtime services. Windows Workflow Foundation (WF) is a technology for defining, executing, and managing workflows.

Throughout the book, an example "bug reporting" workflow system is developed, showcasing the technology and techniques used. Fast-paced and to-the-point, this book takes you through the important topics of Windows WF development with clear explanations and practical example code. The book's selection of topics is driven by what the working developer needs to know. It is neither a comprehensive reference to the whole WF architecture, nor a strategy guide to the complete application development lifecycle. It's just what you as a C# developer need to know to use WF in your applications. This book is for .NET developers who want to enhance their applications with flexible workflow capabilities using Microsoft Windows Workflow Foundation. The author assumes that you have read other texts on the overall architecture of WF and on WF application design strategies, and instead focuses on real-work implementation issues for C# developers.
