We just uploaded to our corporate site a small sample we created for the Windows Vista Launch in Colombia, showing some features in Windows Communication Foundation, Windows Workflow Foundation and BizTalk Server 2006.

The sample showcases a simple business scenario that uses features like WCF self-hosted services, multiple bindings (HTTP and TCP) and callback contracts. The service is consumed by a simple WinForms client, as well as a simple State-Machine Workflow that uses the HandleExternalEvent activity to receive events fired by the WCF service, as well as my own custom MSMQ activities to fire messages off to BizTalk for further processing. (Notice we focused on the core features and keeping the code simple to showcase them, so the sample lacks quite a bit of error handling).
