Now that I have shipped WSE 3.0, a year to the day that I started on the project, a number of people have asked me, "What's next to fill the empty WSE void?" Well, WSE has always been very closely aligned with the security team in Windows Communication Foundation (WCF aka Indigo), so that is the natural place for me. Effectively I now work on getting the security features done in WCF, but I will still be writing WSE articles. The one that I have planned is "WCF for WSE 3.0 Developers" to help with the mental mapping between the two products.
