Windows Communication Foundation ("Indigo") & Windows Workflow Foundation "Go-Live License"
Customers have been patiently waiting for the ability to release solutions they have built using Windows Communication Foundation (WCF), née "Indigo", or Windows Workflow Foundation (WF). With today's "Go-Live License" announcement, the wait is officially over.
The license allows customers to deploy the January releases of WCF and WF in production environments. One caveat is there is no official support from Microsoft. However, the WCF and WF community sites are excellent venues for receiving assistance from other customers and the product teams. The sites also have sample code galleries to help you get started.
