.NET - Windows Workflow Foundation

According to Microsoft, there are four major principles that explain the behavior and working of workflows. Developers can use these principles while developing workflow-based applications. The four principles are as follows:

• Workflows help in coordinating the work performed by people and software.
• Workflows are long-running and stateful.
• Workflows are based on extensible models.
• Workflows remain transparent and dynamic throughout their lifecycle.

The base activity library is a collection of activities used to create workflows.

WF provides developers a declarative way to create workflows by using extensible Application Markup Language (XAML). The files used to store such workflow markups are known as extensible Object Markup Language (XOML) files.
