Change WCF service to accept content-type “application/xml;charset=utf-8”

Question

I created WCF service that's going to be consumed by a third-party that needs to accept content-type application/xml;charset=utf-8 and SOAP 1.1 envelope namespace. The service is currently accepting text/xml;charset=utf-8. Having the client change the content-type is not an option.

I haven't made any changes to the web.config file, except setting the basicHttpBinding maxReceivedMessageSize.

  <bindings>
      <basicHttpBinding>
        <binding name="http" maxReceivedMessageSize="2147483647"/>
      </basicHttpBinding>
    </bindings>

This issue typically due to the service type. Traditional SOAP web service based on the web service specification, SOAP envelope is the communication carrier and content-type is “application/soap+xml; charset=utf-8” or “text/xml;charset=utf-8”(for compatible with XML web service).

The specifical HTTP header is commonplace in the Restful style service. WCF could create a restful style service too.
