I know this notice is late, but I will be presenting a talk entitled "BizTalk Server 2006 R2 and the WCF Adapters" to the Denver BizTalk User Group tomorrow.  Here's the link to the event:

BizTalk User Group: BizTalk Server 2006 R2 and the WCF Adapters

The event will take place at the Denver Microsoft building at the following address:

Maroon Bells Room
7595 Technology Way
Suite 400 Denver Colorado 80237
United States

Here's the event abstract ...

BizTalk Server 2006 R2 provides new adapters that enable simple communication to and from BizTalk Server and Web services-based applications via the Windows Communication Foundation (WCF). Through the WCF Adapter SDK you can utilize these new extensions to write WCF-based transports to expose existing technologies and applications. We will discuss real world uses for the WCF adapters and provide a demonstration of these adapters in action.

I'll post my slide deck and some bits after the presentation.  I hope to see  you there!
