Hi,

Original intention is to create a service with Transport level security using SSL certificate and also enable Message level security with another server certificate but without any client authentication (Anonymous clients)

Is there some correct way of doing this?

When I setup

<security mode="TransportWithMessageCredential">

with

<message clientCredentialType="None" />

for wsHTTPBinding, I get an exception

InvalidOperationException: ClientCredentialType.None is not valid for the TransportWithMessageCredential security mode. ...

Thanks in advance.
