My WCF service[using basicHttpBinding] is hosted on IIS 6.Am able to access it using ?wsdl in the service url in IE browser .

I’ve a presenation layer in my winforms client and I added the reference of this service using ServiceReferences option in VS.Net which then generated a proxy.

When I call a method on this service, am getting this exception.What could I be missing here ?Thanks.
