The value specified for the AuthenticationScheme property on the HttpTransportBindingElement ('{0}') is not allowed when building a ChannelFactory. If you used a standard binding, ensure the ClientCredentialType is not set to HttpClientCredentialType.InheritedFromHost, a value which is invalid on a client. If you set the value to '{0}' directly on the HttpTransportBindingElement, please set it to Digest, Negotiate, NTLM, Basic, or Anonymous.
