Question

Have just deployed a WCF project to IIS.

However when I try to add the service reference to a test project, Visual Studio gives the following:

The document was understood, but it could not be processed.
  - The WSDL document contains links that could not be resolved.
  - There was an error downloading 'http://server1.local/WCFServices/serv1/serv1.svc?xsd=xsd0'.
  - The underlying connection was closed: An unexpected error occurred on a receive.
  - Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
  - An existing connection was forcibly closed by the remote host
    Metadata contains a reference that cannot be resolved: 'http://server1.local/WCFServices/serv1/serv1.svc?wsdl'.
    Content Type application/soap+xml; charset=utf-8 was not supported by service http://server1.local/WCFServices/serv1/serv1.svc?wsdl.  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.

So there’s a problem, which I sorta get. The content type of the service is mismatched from what the client is expecting.

So, how do I fix it?

Answer 1

Check the App.Config or Web.Config of your client and check the ServiceModel. Most probably there is a customBinding which is different from what the WCF service is sending.
