When we discuss Windows Communication Foundation (WCF) with ISV's, many of the questions we often hear relate to interoperability with other platforms, communication technologies, standards, etc.

Jorgen Thelin is the Senior Program Manager for Connected Systems Interoperability Standards at Microsoft, and leads our efforts to make sure that our core products like WCF have the best interoperability story in the industry.  He has an active blog that discusses the interoperability efforts by Microsoft overall including this recent post about Interoperability using Windows Communication Foundation (WCF).

Are we missing the boat on any interoperability scenarios that you care about?
