Chilkat.Socket listenSocket = new Chilkat.Socket();

bool success;
success = listenSocket.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    Debug.WriteLine(listenSocket.LastErrorText);

}

//  Pass a value of 0 for the port number to randomly select
//  an unused port.
//  (The 2nd argument allows for a backlog of 25 pending connection requests when accepting connections.)
success = await listenSocket.BindAndListenAsync(5555,25);

    Debug.WriteLine(listenSocket.LastErrorText);
    return;
