Microsoft announced Go Live licenses this morning for WCF (Windows Communication Foundation / “Indigo”) and WF (Windows Workflow Foundation), which allow customers to use the January Go Live releases of WCF and WF in their deployment environments.  (Note that these are unsupported Go Lives.) 

More information about the Go Live program is at http://msdn.microsoft.com/winfx/getthebeta/golive/default.aspx.

There are also WCF and WF community sites, at:

http://windowscommunication.net

http://windowsworkflow.net

The community sites are intended to give users everything needed to start using WCF and WF today.
