"Microsoft Windows Workflow Foundation 4.0 Cookbook" 《Microsoft Windows Workflow Foundation 4.0 Cookbook》是一本专为开发者准备的实践指南，它涵盖了超过70个关于创建工作流的实用解决方案。作者Andrew Zhu通过一系列手把手的教学和即用型的示例，帮助读者深入理解和应用Windows Workflow Foundation（WF）4.0这一强大的技术。 Windows Workflow Foundation是微软.NET Framework的一部分，是一个用于构建业务流程和工作流应用程序的框架。WF4.0版本带来了许多改进和新特性，旨在提高开发效率和灵活性。本书的重点在于提供实际的代码片段和实例，帮助读者快速掌握如何利用WF4.0来设计、实现和管理复杂的工作流。在书中，读者可以学习到以下关键知识点： 1. **工作流基础**：理解工作流的概念，包括活动、状态机工作流、顺序工作流以及工作流的生命周期管理。 2. **设计工作流**：学习使用Visual Studio工具创建和编辑工作流，包括基本活动、控制流活动和数据流活动的使用。 3. **工作流服务**：探索WF4.0如何与WCF（Windows Communication Foundation）集成，创建基于服务的工作流，以实现服务间的交互。 4. **持久化与跟踪**：了解如何保存和恢复工作流状态，以及如何设置跟踪以进行调试和性能监控。 5. **规则引擎**：学习使用WF4.0内置的规则引擎，以声明式方式定义业务逻辑。 6. **自定义活动**：掌握创建自定义活动的方法，以便扩展WF4.0的功能，满足特定业务需求。 7. **工作流宿主**：学习如何在各种应用程序环境中（如ASP.NET、Windows服务等）托管和运行工作流。 8. **错误处理与补偿**：了解如何处理工作流中的异常和错误，以及如何设计补偿机制以确保事务的原子性。 9. **工作流版本控制与迁移**：探讨如何在不中断服务的情况下升级和迁移工作流实例。 10. **工作流设计模式**：研究常见工作流设计模式，如并行执行、循环和决策分支，以优化流程设计。 11. **工作流管理与监控**：学习使用Windows PowerShell命令和管理工具对工作流进行管理和监控。通过这本书，开发者能够获得在实际项目中实施WF4.0所需的知识和技能，从而更有效地构建灵活、可维护的业务流程系统。尽管书中可能无法涵盖所有可能的场景，但它为开发者提供了一个坚实的基础，使他们能够进一步探索和适应WF4.0的广泛可能性。

Preface

WF4 is a process engine, as well as a visual program language, shipped along with Microsoft

.NET Framework 4.0. Traditionally, when we design a long-running application, we break

a large application into lots of small code blocks to address the business logic and use a

database to store the intermediate data. With the growing complexity of logic, managing code

blocks and authoring logic workows becomes difcult. Now, with WF4, we can design and

create distributed, long-running programs easily.

The aim of this book is to provide a step-by-step guide to help us start WF4 programming.

Every recipe in this book is runnable.

What this book covers

Chapter 1, Workow Program, provides recipes that will help us understand basic information

about WF4 programming.

Chapter 2, Built-in Flow Control Activities, provides recipes that demonstrate the usage of the

built-in control activities.

Chapter 3, Messaging and Transaction, provides recipes that demonstrate how to send and

receive WCF messages in workow. The second part of this chapter focuses on applying

transactions in a workow program.

Chapter 4, Manipulating Collections, demonstrates how to manipulate collection data in

workow programs with WF4 built-in activities.

Chapter 5, Custom Activities, demonstrates how to create our own custom activities; the most

powerful unit of workow.

Chapter 6, WF4 Extensions, demonstrates how to use the built-in extensions such as

persistence and tracking, and also how to create our own extensions.

Preface

Chapter 7, Hosting Workow Applications, mainly explains how to host workow applications

in IIS7. This chapter also provides recipes that demonstrate host workow in ASP.NET, WPF,

and Windows Forms.

Chapter 8, Custom Workow Designer, helps us create our own WF4 workow designer with

visual tracking function.

What you need for this book

We need a PC having Windows Vista/7/2008/2008R2. We can also use Windows XP, but it

is not recommended. .NET Framework 4.0 is a must. Once we install .NET Framework 4.0, we

can run workow applications. To develop WF4 workow applications, we should also have

Visual Studio 2010 installed on our computer. To host WF4 as a WCF service in IIS, we should

install IIS7/7.5 in our computer.

Who this book is for

If you nd yourself working with Windows Workow Foundation 4.0 and you have basic

knowledge of C#/.NET Framework/VB and workow, this book is for you. It will be best if you

know both C# and VB, because WF 4.0 expressions can be written only in VB (at the time of

writing). With this book, you will be able to enhance your applications with exible workow

capabilities using WF 4.0. To follow the recipes, you will need to be comfortable with .NET

Framework, C# programming, and the basics of SOA and how to develop them.

Conventions

In this book, you will nd a number of styles of text that distinguish between different kinds of

information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "The

ActivityLibrary project is for all customized

activities, whereas the WorkflowConsoleApp project is used for testing our customized

activities".

A block of code will be set as follows:

class Program {

static void Main(string[] args) {

WorkflowInvoker.Invoke(GetCodeStyleWorkflow());

}

Any command-line input or output is written as follows:

.NET Framework 4 Full (32-bit) – silent repair

%windir%\Microsoft.NET\Framework\v4.0.30319\SetupCache\Client\setup.exe /

repair /x86 /x64 /ia64 /parameterfolder Client /q /norestart
