Windows Workflow Foundation library is a new addition to Windows Vista suite of libraries. It allows developers to create Workflow based applications. This article is a basic introduction of Windows Workflow Foundation (WWF) library and shows how to write your first WWF application using Visual Studio 2005. In my forthcoming articles, I will explain WWF in more details.
What is a Workflow?
Workfllow based applications have been arround for a while and usually being used in Enterprise development. A workflow is a set of activities represented in a declarative languages such as XML. Each activity in a workflow is a set of actions to be taken in respect to some business logic. In other words, an activity is some peice of code that executes some business logic.
Windows Workflow Foundation (WWF)
In WinFX world, the API that is used to create workflow based applications is called Windows Workflow Foundation (WWF). The WWF provides you a choice to write your workflow solely in XAML (see XAML section to learn more about XAML) or a combination of XAML and a .NET programming language such as C# or Visual Basic. If you write a workflow in an XAML file only, there is no need to compile the code. All functions will be loaded dynamically at run-time. However, if you use a combination of a code-behind file and XAML, then you will have to compile the code.
Creating Workflow Based Applications using Visual Studio 2005
Visual Studio 2005 supports workflow based applications.
To create a workflow based application, select New Project and select Workflow option from the list. You should see various workflow based templates in the Templates section. See Figure 1.
Figure 1. Selecting a Workflow based template in Visual Studio 2005
Note. You must have to install WinFX SDK before you can see Workflow templates. See Getting Started with the December 2005 WinFX CTP by Doug Cook on how to get started with the latest CTP.
As you can see from Figure 1, there are 6 templates (described below) installed in current version of Visual Studio to create 6 different types of Workflow applications.
- Sequential Workflow Console Application
- Workflow Activity Library
- State Machine Workflow Library
- Sequential Workflow Library
- State Machine Console Application
- Empty Workflow Project
In this article, I will use one of these templates to create our first workflow based application.
