I've been struggling for a few days with this problem, learning a lot of things on bindings in the process. One thing puzzles me, though: various links (see this or that for example) explicitly state "By default, WCF project is created using WsHttpBinding", but that's not what I see. This is what I do:
- Open Visual Studio 2010 and choose New Project / Visual C# / WCF Service Application
- Don't touch anything inside the code, set a local IIS Url for the service (say http://localhost/WcfService7)
- Open soapUI and choose File / New Soap UI Project / enter the url of the newly created wsdl: http://localhost/WcfService7/Service1.svc?wsdl, not touching any other option
- Interface properties: SOAP Version = SOAP 1.1, Binding = "BasicHttpBinding_IService1" (even though it's just a name, it's a hell of a hint)
- Open Altova XmlSpy and choose SOAP / Create new SOAP Request / enter the url of the wsdl / select any operation
- SOAP / Change SOAP Request parameters / Ensure that "Send as SOAP+XML (SOAP 1.2)" is checked
SOAP / Send request to server: i get the errors
HTTP error: could not POST file ‘/WcfService7/Service1.svc’ on server ’localhost’ (415)
Error sending the soap data to ‘http://localhost/WcfService7/Service1.svc’ HTTP error: could not POST file ‘/WcfService7/Service1.svc’ on server ’10.51.0.108’ (415)
Any explanations? Thanks
