Creating a task-based WCF service
There's not a great deal of change in Visual Studio 2013 for Windows Communication Foundation (WCF) development. However, don't misread that as there's not a lot of improvement for WCF developers in the .NET Framework 4.5.X. It's simply that since WCF is a technology focused on network communications, the visible changes in Visual Studio are quite small.
Tip
WCF is Microsoft's framework designed for use in creating applications based on service-oriented architecture. Some of the features provided by WCF include interoperability, service metadata, data contracts, and security. For in-depth information on using WCF, refer to http://msdn.microsoft.com/en-us/library/dd456779(v=vs.110).aspx.
The only visible changes are in the Add Service Reference dialog box 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. A sample WPF application will call this sample WCF service.
