In order to use WCF (Windows Communication Foundation) you first need to register it with IIS. In order to accomplish this you need to use the ServiceModelReg.exe tool supplied when .Net 3.0 is installed on your system.
You can find the utility under C:\WINDOWS\Microsoft.NET\Framework\v3.0\Windows Communication Foundation\ServiceModelReg.exe and run it in a console with the flag -i (ServiceModelReg.exe -i).
