Windows Workflow Foundation

Windows Workflow Foundation is a new class Library added by. Net 3.0.

 

I remember a long time ago, when I went to college, I had a hard time programming. I thought it would be nice if I could change the design process and write the program.

However, my personal abilities are limited, and I am not a computer professional.

 

But I did not expect that Microsoft actually implemented this idea. This is WWF.

 

However, WWF is mainly used to process more forms in transaction processing, which is different from my original idea.

But it is already a good breakthrough.

 

Microsoft Windows Workflow Foundation (WWF) is an extensible framework for developing workflow solutions on Windows platforms. As part of Microsoft winfx, Windows Workflow Foundation provides APIs and tools for developing and executing workflow-based applications. Windows Workflow Foundation provides a single unified model to create end-to-end solutions for applications across multiple categories, including human workflows and system workflows.

Windows Workflow Foundation is a widely used workflow framework. It is designed for scalability at all levels from bottom to top. A Windows Workflow Foundation-based solution consists of Interconnect components that are supported by Microsoft. NET code and run in the Host application. Just like creating web pages visually in a custom environment, you need to develop specific workflow steps in the visual designer, add the code to hide the workflow component to implement the rules and define the business process.

Windows Workflow Foundation provides a workflow engine, A. Net managed API, A Runtime Library Service, and a visual designer and debugger integrated with Microsoft Visual Studio 2005. You can use Windows Workflow Foundation to generate and execute workflows that span both the client and server, and workflows that can be executed within all types of. NET applications.

This article provides a smooth introduction to Windows Workflow Foundation through several step-by-step examples and describes how it works.

WorkflowA human or system process model defined in the form of activities.ActivityIs a step in a workflow, and is the execution, reuse, and Creation Unit of the workflow. Activities express rules, operations, statuses, and their relationships. The Windows Workflow Foundation workflow is designed by arranging activities, which is then compiled into a. Net assembly and executed in the workflow Runtime Library and the Common Language Runtime Library (CLR.
