The
StartSocketServer()
method is called to put the server to work. It creates a
Socket
object and
configures it using the specified port. This method is hard-coded to use the
localhost
address. Once the end
point is configured, the
Socket
object's
BeginAccept()
method is called. This will invoke the specified callback
method (
OnConnect
) when a new connection is received. The
MessageReceived()
event handler simply writes
the input message to the console and echoes the message back to the client. The
WsConnection
