I am Writing a PHP application that needs to run a back end .NET application. When creating a running the WCF web service out of the box, the PHP could not connect to the web service.

The problem:

The PHP returns "Caught exception: Cannot process the message because the content type 'text/xml; charset=utf-8' was not the expected type 'application/soap+xml; charset=utf-8'."

The reason:

WCF is running a new version of web services than expected by the PHP.
