An interesting question on Stackoverflow.com: .net – Different WSDL ASMX,WCF web-services – Stack Overflow.
The answer is simple when you know it: flatten the WSDL that comes from WCF.
Note that Delphi Win32 is not the only client having these issues, as Elton Stoneman shows on his blog and the WCFExtras toolkit for WCF that allows for single WSDL export.
