Packaging Workflows into .NET Code Libraries

The previous lab had you build a console-based workflow application. Using this project template, the workflow and runtime hosting logic are compiled into a single executable.

In a production-level environment, it would be preferable to package workflows in a dedicated .NET *.dll. By packaging workflow instances into a .NET code library, you are able to model common business processes that can be reused easily at a binary level. Therefore, any sort of .NET application (ASP.NET, Windows Forms, WPF, console programs, other *.dlls, and so on) can make use of the same business processes. Obviously, this is helpful, particularly when a particular business process, such as credit card validation, may need to be reused among multiple projects.

Recall that Visual Studio provides Sequential / State Machine Class Library projects. These templates will provide you with the same design-time experience as seen in your previous lab.


Client applications will reference this *.dll just like any other .NET library. The client application will also need to construct the infrastructure manually to host the workflow instance in the WF runtime.
