PlatformNotSupportedException

The AuthenticateAsServerAsync method is not supported on Windows 95, Windows 98, or Windows Millennium.

This method authenticates using Default. The certificate revocation list is not checked during authentication. The client is not required to provide a certificate for authentication.

If the authentication fails, you receive a AuthenticationException, and this SslStream is no longer useable. You should close this object and remove all references to it so that it can be collected by the garbage collector.
