Bind and Listen for Incoming Connections

See more Socket/SSL/TLS Examples

Demonstrates Socket.BindAndListen, which binds a TCP listener to a port and places it into listening mode, then accepts an incoming connection.

Background. The backlog argument bounds the queue of pending connections. When ClientIpAddress is empty, the listener binds to all interfaces. After listening, call AcceptNext to accept connections.
