There's not a great deal of change in Visual Studio 2012 for Windows Communication Foundation (WCF) development. However, don't misread that as there's not a lot of improvement for WCF developers in .NET Framework 4.5, as that's far from the truth! It's simply that since WCF is a technology focused on network communications, the changes in Visual Studio 2012 are quite small.
The only visible changes are in the Add Service Reference dialog and the IntelliSense support for WCF configurations.
In this recipe you'll create a Task-based WCF service so that you can see what has changed.
Simply start Visual Studio 2012 and you're ready to go.
