If you are interested in deploying an application built with Windows Communication Foundation (WCF) and/or Windows Workflow Foundation (WF) in a live operating environment, please read on. Overview The Microsoft license terms for the above referenced beta software releases do not permit use of the software in a live operating environment. In response to strong customer demand, Microsoft has made available supplemental license terms (referred to as "Go-Live License") for the above referenced releases of Windows Communication Foundation and Windows Workflow Foundation. Subject to compliance with the Go-Live License, the terms will permit limited deployment of these technologies in live operating environments. For each of the technologies, a separate download is provided. The Go-Live License applies for both technologies.
