[Stick to the top] Keep learning WfArticleIndex Activity) An activity is the basic unit of a workflow. Each workflow contains several activities and is executed according to certain logic. There are two types of WF: simple activity and compound activity. WF provides a set of standard activity libraries, and you can also customize the activity. All activities are inherited from activity classes. Below is

With the advent of Windows Workflow Foundation (WF), Microsoft has gradually introduced various workflow functions to the. NET developer platform. These functions enable developers to build workflows that meet various application needs, from simple ordered workflows to complex state machine workflows that require complex human interaction. At the same time, business capabilities are increasingly presented through encapsulated service endpoints, so t

have been curious about WF learning, hey, today will not, I have to contact the WF project, just began to search for WF new project on Baidu process, found that few such instances let me learn to operate, I want to give me a big project I also can not know how to operate, Because the contact is the site and management system production, so now the

In the previous article, we mentioned that Sharepoint is a workflow platform that encapsulates event-driven interfaces on top of the WF workflow engine. SharePoint expands many activities on WF, among them, there are three common activities closely related to WF: onworkflowactivated, createtask, and ontaskchanged. A simple SharePoint Sequential stream. Onw

After completing this chapter, you will learn: 1. Understand the main differences between the procedural (imperative) workflow model and the declarative (declarative) workflow model 2. Create a declarative workflow 3. Use XAML XML vocabulary to create workflows 4. Transfer into a XAML based workflow and execute Many developers may not know that WF can execute workflows using a procedural definition (using the Workflow View Designer), as well as u

1. OverviewWindows Workflow Foundation (WF) is designed for Microsoft products and related applications.ProgramProvides design platforms and development tools. A workflow represents a different programming model-a model that clearly separates work content from work time. A workflow usually uses a declarative rather than procedural programming model. A workflow is composed of activities. All activities and workflows are derived from the system. workf

When creating a new workflow, you must make an important decision: Is the workflow we want to create an ordered workflow or a state machine workflow? WF provides two out of the box workflow execution types. To answer this question, we have to decide who is under control. A sequential workflow is a predictable workflow. The execution path may be a branch, loop, or wait for an external event to occur, however, the final sequence workflow uses the activi

I have been working on WF recently and have encountered some problems and experiences to share with you and discuss them. This issue focuses on exception handling. As far as I know, in WF, once a process instance is started, whether it is running correctly or wrong, whether it is a systemic error or a business error, the instance status is eventually migrated to the closed status and serialized. Of course,

1 workflowruntime. startruntime () Start WF runtime.2 workflowruntime. createworkflow () returns the newly created WF workflow instance. This method prepares a scheduler and a scheduler work queue for the newly created WF workflow instance. When this method is returned, all activities in the WF workflow are in the init

1.1Hour 1-understanding Windows Workflow Foundation1.1.1What workflow are in general A workflow is logic-consisting of one, or more steps, that's predicated by one, or more conditions-that a system or person Must perform to complete a function. Because the logic or process automated by a workflow generally consists of more than one step so may occur over a period Of time, it must track the state of the overall process. Here is some examples of workflows:an order process, an expense repo

This is a WPF workflow designer, Prepare to develop a process designer for Silverlight. A previous graphic UI example has been released. This example is the DEOM before the official development of Silverlight. In addition, most of the articles on architecture are about [Data Service Platform (front-end UI + middle layer + Data Storage)], and the architecture design of tool applications is relatively less. if you are interested in this architecture design, please refer to this article.

Workflow persistence stores certain State information of a workflow to persistent storage, such as SQL databases and files. Once saved to persistent storage, the workflow can be removed from the memory, load as needed. WF persistence service The WF runtime engine provides a series of underlying function libraries for executing and managing workflow lifecycles. The runtime engine architecture is highly scala

1. Summary We have been familiar with the basic concepts of WF before, and I believe you are eager to try it. I want to enter the real WF development. From the beginning of this article, we will first familiarize ourselves with the activities in WF. 2. Activities The core of WF is a series of activities.
