What’s new in WCF 4.5? a single WSDL file

This is the second post in the WCF 4.5 series, and this time we’ll talk about WSDL files. A few weeks ago I posted about the difference between exposing the service metadata through WSDL and through a MEX endpoint, and one of the differences was that using WSDL requires getting several files - WSDL and XSDs. With WCF 4.5, we can now get a single WSDL file that contains all the metadata.
