WCF IClientMessageInspector and the incoming SOAP headers

问题

I'm responsible for updating a client-side API using WCF. This is because of changes to the API on the server (an outside company). When I get the response, my client-side throws an exception. Using Fiddler, I came up with the following problem: a duplicate Content-Type.

HTTP/1.1 200 OK
Date: Thu, 05 Jan 2012 21:15:16 GMT
Connection: close
Content-Type: text/xml; charset=utf-8
Content-Type: text/xml; charset=UTF-8
Content-Length: 538
   ...

Using Fiddler, I removed the extra Content-Type, and the client continued happily. So, I wrote an IClientMessageInspector, with the intention of capturing the response and removing the duplicate. And therein lies my issue. My IClientMessageInspector gets a call to BeforeSendRequest, but not one to AfterReceiveRequest.

Is there some place other than AfterReceiveRequest that I should be handling my task of removing the extra Content-Type? Am I barking up the wrong tree altogether?
