VB.NET Core Classes in a Nutshell

Name

TcpClient

Synopsis

This class provides a client-side abstraction of the sockets API. The zero-argument form of the constructor creates the client. Connect to a remote server with the Connect() method (you must specify an existing System.Net.IPEndPoint or a remote IP address and port number). Alternatively, use an overloaded form of the constructor to simultaneously create the client and make the connection.

This class completely obscures the underlying socket. However, the GetStream() method returns a NetworkStream that you can use to send and receive data across the network.
