I am trying to generate a single wsdl file for a wcf service for which .net framework version is 4.7.2. I see this link says it is supported by default in WCF 4.5 version. When I try to access ?singleWsdl of the service, it still throws an error "System.NotSupportedException: A single WSDL document could not be generated for this service. Multiple service contract namespaces were found".
Any idea why it does not work ? Thanks for any help!
