Windows Workflow Foundation

Microsoft Windows Workflow Foundation (WWF) is an extensible framework for developing workflow solutions on the Windows platform. It provides both an API and tools for the development and execution of workflow-based applications.

Having done no testing, I could only guess at the answer. I’ve now undertaken some initial performance testing to compare WF and MS BRE, and decided to publish the results. You can read my write-up of the results here. http://geekswithblogs.net/c... ......
