Webservice returns wrong content-type response header

Question

I am trying to use third-party web service (php-based) in asp.net c# application, and failed with service configuration.Already tried add service/web reference - all the same error :

The content type text/html of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 402 bytes of the response were: '<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body>;<...

[Response was edited manually to correctly display > < chars, it's perfectly valid otherwise]

To me it seems like a perfectly valid response, and I tried to look at what fiddler writes in response headers - Content-Type: text/html, which is probably the source of issue - webservice sents wrong content-type (text/html instead of text/xml) , but how to configure my client to ignore/override received content-type ? Googling gets me nothing so please, if anyone could help - where problem is? Binding\endpoint configuration is a default basicHttpBinding/endpoint which is generated by VS2010 when using Add Service Reference option, nothing was changed there. Thanks in advance.

Answer 1

Perhaps overkill, but you could try with a custom encoder for the binding. Default is text/xml.

I am not sure but do you think you are running into what is shown here: http://cushen.wordpress.com/2009/04/08/web-service-content-type-error-using-visual-studio-2008/

Seems pretty similar.. You should use Add Web Reference vs Add Service Reference (since the latter is for WCF style services?)

Maybe.. :)
