Short Description Get hands-on, step-by-step guidance for using Windows Workflow Foundation to create process-managed applications for Microsoft Windows. This reference offers practical instruction and a CD with practice files and code samples. Long Description Get hands-on guidance for using Microsoft Windows--one step at a time. Understanding Windows Workflow Foundation is essential for every developer who works with multiple applications and services that must exchange data or results. Windows Workflow Foundation defines a process flow amongst people, applications, and services--mapping dependencies and sequences to allow automation of tasks across previously stand-alone programs. With Step by Step, you work at your own pace through hands-on, learn-by-doing exercises to understand the core capabilities and fundamental techniques for working with Windows Workflow Foundation. New-to-topic developers can take a sequential approach to understanding workflows and learning how to create Windows Workflow Foundation--enabled applications and services. This book includes a CD with practice exercises and code samples to help developers accelerate their productivity. Window Workflow Foundation is the programming model, engine, and tools for quickly building workflow-enabled applications on Windows. It consists of a WinFX namespace, an in-process workflow engine, and designers for Microsoft Visual Studio 2005. Windows Workflow Foundation is available for both client and server versions of Windows. It includes support for both system workflow and human workflow across a wide range of scenarios, including workflow within line-of-business applications, user interface page-flow, document-centricworkflow, human workflow, composite workflow for service-oriented applications, business rule-driven workflow, and workflow for systems management. A workflow is a set of activities stored as a model that describe a real-world process. Work passes through the model from start to finish; activities might be executed by people or by system functions. Workflow provides a way of describing the order of execution and dependent relationships between pieces of short-running or long-running work. Although it is possible to write a workflow completely in code, workflow is often best viewed graphically--consequently, Windows Workflow Foundation includes a visual designer. After a workflow model is compiled, it can be executed inside any Windows process including console applications, forms-based applications, Windows services, ASP .NET Web sites, and Web services. Windows Workflow Foundation will be available for Windows Vista, as well as for Microsoft Windows XP and Microsoft Windows Server 2003.
