After you have completed this chapter, you will learn:
1. Use workflow in your application
2. Understand the basic functions of the "WorkflowRuntime" object
3. Know how to start and stop the workflow runtime
4. Ability to use a variety of workflow runtime related events
When you perform a task in a WF environment, you need something to oversee the execution process, which is the object named "WorkflowRuntime". WorkflowRuntime to start a separate
Everyone knows that in WF, by default, its activities are composed of tree structures. Simply put, a composite activity contains its subactivities. If a subactivity is a composite activity, it can also contain its subactivities, however, a single activity cannot be a subactivity of two activities. This method is widely used in the activity library of WF, such as loop and conditional activity.This method has
After completing this chapter, you will learn:
1. Learn which components are required to create a full-featured custom workflow activity
2. Create a basic custom workflow activity
3. Apply validation rules in basic custom workflow activities
4. Integrate basic custom workflow activities into the Workflow View Designer and toolbox of Microsoft Visual Studio
WF is not likely to cover every aspect of what you might want to achieve in your workflow.
Since October 09 NET4.0 Bata 2 Released, I began to write [WF4.0 Basic article] This series, after 5 months after the NET4.0 officially released the series completed.
This time with some of the companies interested in WF4.0 and developers have some exchanges.
Let's talk about companies that are interested in WF, some companies have started to use WF4.0 to develop business process management software, these companies and I communicate with many of th
WF (Windows Workflow Foundation, the Foundation for Windows Workflow) is a programming language based on more advanced abstraction concepts that is suitable for implementing business processes. Although you can create WF programs by using a graphical tool (Workflow Designer), developers can use XAML (extensible Application Markup Language, Extensible Application Markup Language), To take full advantage of t

[WF] Quickstart sample Preface
Workflow Foundation (WF) always gives a very useful impression, but does not know how to use it. This is mainly because there are too many pre-jobs and a lot of underlying knowledge need to be integrated to complete writing: Execute activity, pause activity, re-read activity, continue activity, this series of workflow.
The following example is a record of my learning about Wor
1 Net Designer Foundation framework
The namespace for the. NET designer infrastructure is System.ComponentModel.Design, and the three designer architectures for WF, ASP.net, and win from are all built on. NET itself provides the underlying framework.
The namespace for the WF designer frame is System.Workflow.ComponentModel.Design, and the related classes are in the namespace. Before researching
WF workflow instance persistence (passivation) is very important in workflow projects. In actual business, almost all business flows can be completed after a long time, in this way, the unfinished business flow needs to be persisted to the database or file.
WF itself provides the sqlworkflowpersistenceservice service to support instance persistence.

This article mainly introduces the basic knowledge of the state machine workflow in WF. The state machine workflow and sequential workflow are different. Ordered workflows are generally relatively fixed and predictable, and there are many interactions with the system. State Machine workflows are generally unpredictable, and there will be more interac

WF regularly checks the persistence point and saves the workflow instance to the persistent storage. In this way, information related to the workflow is stored if an error occurs or the workflow ends abnormally, the next time the workflow instance is loaded, it will start from this point. This is mainly for work-embedded services. The external ser
When I recently studied WF, I encountered an unknown error, such as the error message.

WF. data. when taskactivity constructor executes a call that meets the specified binding constraints, an exception is thrown. ".
1. Summary
In the above article, we used ifelse to simulate a login process.
In this article, we will use while to simulate a guessing game.
In recent articlesArticleI will have some simulated small examples to explain the usage of the specific active control, but it is just a small example. In actual engineering, we all use WF to build an overall macro framework process. This is not a small example and we hope you will be familiar with it.
WF 4.0 RC has been released, but it has not changed much compared with Beta 2: wf4.0: RC compared with beta2, it seems that the wf4.0 state machine workflow cannot be released with vs2010, you can only wait for an independent SDK or the next version. In general, RC has determined all content of wf4.0. If you want to know WF 4.0 RC, you cannot miss the following resources.

Windows Workflow Foundation is not a business workflow platform, but a group of APIS for process development. It provides good thread management, process scheduling, Object persistence, and exception handling, basic functions of transaction processing.
Whether a workflow project is successful depends on the project analysis and design, and does not depend on what new technologies are used.

Design business process platform based on WF _ participants and task list
Participants are involved in the process (it seems a bit nonsense ),
Here, I will briefly describe the participants. I will explain more in the following articles about resources.
From the workflow perspective, there are three types of persons related to the process:
Participants

After completing this chapter, you will learn:
1. Learn how each workflow activity is designed to be used to expose your workflow to XML Web services
2. Understand what it takes to host workflows in asp.net
3. See how error (Fault) is handled in workflows based on XML Web services
4. Configure your workflow for xml-based Web services for a variety of situations
In the previous chapter, "Invoking Web Services in your workflow", you saw how to invoke an XML Web service using the Invokewebserv
