Windows Communication Foundation (WCF) is a system for creating connections between applications using services and endpoints. WCF is, more than anything, an infrastructure technology for messages. Just as roads support cars, and as electricity travels
over wires and cables, and as pipes convey water, WCF exists to transfer messages between any two endpoints. And it does so
securely as well. That is, you can create messages that are encrypted to keep your information safe from criminal minds.

Other forums that touch on WCF topics include the Workflow forum,
AppFabricService and Workflow Management forum, and the
ASMX Web Services and XML Serialization forum.
Of course, you are now on the WCF wiki. The wiki allows you to add your personal knowledge and expertise to a public forum. If an existing topic needs work, and you have the expertise, please fix it. Or if
you have knowledge that would be useful to others, create a new page to share it.
