Refactor channel class names to use Client prefix.
Instead of UaTcpSessionChannel, use ClientSessionChannel. See Readme for details.
// create a 'ClientSessionChannel', a client-side channel that opens a 'session' with the server.
var channel = new ClientSessionChannel(
clientDescription,
null, // no x509 certificates
new AnonymousIdentity(), // no user identity
"opc.tcp://opcua.rocks:4840", // the public endpoint of a server at opcua.rocks.
SecurityPolicyUris.None); // no encryption
