In Internet-based WCF services, security is a very important part. There are many security modes in WCF. This time, we will consider using a limited server environment (such as a virtual host) to configure the message security mode for X509 Certificate authentication. Generally, in this extreme environment, it is difficult to implement SSL-based transmission security. Therefore, we consider deploying messag
