WF4.0教程 4.0 基础篇:入门与实践 在这个WF4.0教程系列的第一部分,我们开始探索Windows Workflow Foundation (WF) 4.0,这是.NET Framework 4.0中的一个重要组成部分,旨在简化业务流程自动化和应用程序的逻辑控制。WF最初作为Windows Workflow Foundation (WWF) 在.NET 3.0时代引入,但在.NET 4.0中名称有所简化,去掉了“World Wide Fund for Nature”的混淆。 WF4.0被设计为与Windows Presentation Foundation (WPF) 和 Windows Communication Foundation (WCF) 配合使用,形成一套完整的应用程序架构。WPF负责用户界面(UI)的设计和展示,WCF则处理应用程序之间的通信,而WF则专注于业务流程的定义和执行。这种分离使得开发者能够更加专注于各自领域的核心功能。 教程的结构分为以下几个部分: 1. **开始使用WF4.0**: - **前言**:介绍了WF的历史背景,包括其起源于WinFX CTP版本,并指出WF在.NET 3.0正式发布的价值。 - **创建WF4.0项目**:演示如何在.NET 4.0环境中创建一个新的WF项目,以便进行后续开发。 - **创建'hellowxwinter'屏幕输出工作流**:通过实例化一个简单的WF工作流,展示基本的WF概念,如活动、状态机和转换。 - **程序结构说明**: - **XAML流程结构描述文件**:解释XAML在WF中的作用,它是工作流的可视化表示,易于理解和编辑。 - **宿主程序**:介绍如何将工作流嵌入到Windows Forms或WPF应用中运行。 - **代码方式创建WF4.0工作流**:深入讲解如何使用C#编写工作流代码,实现自定义逻辑。 通过这个基础篇的学习,读者可以对WF4.0有初步的认识,了解其在业务流程自动化中的应用场景,并掌握基本的项目创建和工作流构建方法。随着教程的深入,后续章节将涵盖更复杂的工作流设计、事件驱动模型、数据绑定、异常处理等内容,帮助读者逐步掌握WF4.0的强大功能。

Beginning WF: Windows Workflow in .NET 4.0 By Mark Collins Publisher: Apress 2010 | 500 Pages | ISBN: 1430224851 | PDF | 4 MB Windows Workflow Foundation is a ground-breaking 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 problems. 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. Beginning WF demonstrates, in an eminently readable and accessible style, how Microsoft's Workflow Foundation (WF) technology can be used in a wide variety of applications. Loaded with lots of simple yet demonstrative sample projects Very hands-on with practical "how-to" information Indexed by feature so specific questions are easily answered What you'll learn Beginning WF will take you step by step through many of the useful applications of workflow technology. Along the way, you will: Create designer-based and code-based workflows Communicate between applications using workflow activities Implement SQL persistence with custom participants Create workflow extensions and custom activities Build applications that support long-running workflows Host workflows in WCF services Who is this book for? This book is perfectly suited to anyone using or considering Microsoft's Windows Workflow Foundation. It describes what WF can do for you and how to quickly learn the basic concepts needed to be proficient. If you're actively implementing a workflow project, this book has lots of sample projects that demonstrate the most useful design patterns.
