gSOAP to WCF . Application/soap+xml; charset=utf-8 - c++

Question

I have simple web service running on http://calculator.gear.host/Service1.svc
I have no problem while do call from WCF Test Client and have error while calling from gSOAP c++ client.
HTTP/1.1 415 Cannot process the message because the content type 'application/soap+xml; charset=utf-8; action="http://tempuri.org/IService1/GetData"' was not the expected type 'text/xml; charset=utf-8'.
Packets on Fiddler:

I' have the same problem with a service not generated with gSOAP (probably using some tool in C#).
For your client gSOAP, recompile your WSDL file (soapcpp2.exe) using option -1 (generate SOAP 1.1 bindings).
This works for me.
