what is the \"behaviorConfiguration\" attribute of service?
You will get this error with Behavior name is not setup correctly.
The HTML document does not contain Web service discovery information. Metadata contains a reference that cannot be resolved: 'http://blabla.com/WebService/Processor.svc'. Content Type application/soap+xml; charset=utf-8 was not supported by service 'http://blabla.com/WebService/Processor.svc'. The client and service bindings may be mismatched. The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'.. If the service is defined in the current solution, try building the solution and adding the service reference again.
