Proxy generated for WCF creating Message Contracts

Question

I'm consuming a WCF service in my project for which I've added the reference using 'Add Service Reference...'. I expected it to generate a clean proxy with a ServiceClient entity and the Interface. Instead, I see that it has created a MethodNameRequest, MethodNameRequestBody, MethodNameResponse, MethodNameResponseBody entities for each OperationContract method.

So while invoking the service methods, the proxy passes to the service method an instance of MethodNameRequest with the input parameters of the method as the properties of the RequestBody. See below an example of a call to AboutInformationGet() method which doesn't accept any parameters.

        public WCFDynamicInvocation.PostingService.AboutModel AboutInformationGet() {
        WCFDynamicInvocation.PostingService.AboutInformationGetRequest inValue = new WCFDynamicInvocation.PostingService.AboutInformationGetRequest();
        inValue.Body = new WCFDynamicInvocation.PostingService.AboutInformationGetRequestBody();
        WCFDynamicInvocation.PostingService.AboutInformationGetResponse retVal = ((WCFDynamicInvocation.PostingService.IMIGQPosting)(this)).AboutInformationGet(inValue);
        return retVal.Body.AboutInformationGetResult;
    }

I believe this behavior is what one would expect to see in a Webservice Proxy. Hence I suspect that the WCF service is not properly configured.

Did someone here face this issue? What would be the change to be done at the service so that the proxy generated is similar to the WCF service.

Cheers.

There is a similar post here.

Right click your service reference -> Configure service reference... -> Check if "Always generate message contracts" check box is checked. Uncheck it and hit OK to regenerate the proxy to see if you get a normal proxy.
