When i make a call to a soap WS via WCF i get a null response

Im trying to create a WCF consumer of a soap webservice.

I have created the webservice schema which in the request passes a string argument and gets back a string response, however when i call the service i get back a null response.

Ive looked at the TCP trace of whats going on and everything looks correct, i perform a post and get back an HTTP 200 response with the soap XML contained within.

Ive also tried the same thing using a WebReference and that works as expected (With the same request/200 response pattern), so im kinda stumped.

Is there a way i can plug into WCF to see why it thinks its getting no response or is there some other path i can go down to debug this?

Thanks

I found out what the issue was with this, I needed to decorate the Contract with the following to allow it to work out how to interpret the soap response

    [XmlSerializerFormatAttribute(Use = OperationFormatUse.Encoded)]
    [return: MessageParameterAttribute(Name = "MySoapReturnName")]
