WCF Service Client: The content type text/html; charset=utf-8 of the response message does not match the content type of the binding

Question

I\'ve got a WCF Service running on my local IIS server. I\'ve added it as a service reference to a C# Website Project and it adds fine and generates the proxy classes automa

Answer 1

Try browsing to http://localhost/ScraperService.svc in the web browser on the server hosting the service, using the same Windows credentials that the client normally runs under.

I imagine that IIS is displaying an html error message of some description instead of returning xml as expected.

This also can occur when you have an http proxy server that performs internet filtering. My experience with ContentKeeper is that it intercepts any http/https traffic and blocks it as "Unmanaged Content" - all we get back is an html error message. To avoid this, you can add proxy server exception rules to Internet Explorer so that the proxy doesn't intercept traffic to your site:

Control Panel > Internet Options > Connections > LAN Settings > Advanced > Proxy Settings
