4.5 Networking

The FCL provides a layered set of classes for communicating over the network using different levels of abstraction, including raw socket access; TCP, UDP, and HTTP protocol support; a high-level, request/response mechanism based on URIs and streams; and pluggable protocol handlers (see Section 3.7 in Chapter 3).

For more information, see the following namespaces:

System.Net
System.Net.Sockets

An important related type in another namespace is System.IO.Stream.
