Network Programming

The Microsoft .NET Framework provides a layered, extensible, and managed implementation of Internet services that can be quickly and easily integrated into your applications. Your applications can build on pluggable protocols to automatically take advantage of new Internet protocols, or they can use a managed implementation of the Windows socket interface to work with the network on the socket level.

• System.Net.Configuration
  Contains classes that applications use to programmatically access and update configuration settings for the System.Net namespaces.

• System.Net.Mail
  Contains classes that applications use to compose and send mail using the SMTP protocol.

• System.Net.Mime
  Defines types that are used to represent Multipurpose Internet Mail Exchange (MIME) headers used by classes in the System.Net.Mail namespace.

• System.Net.NetworkInformation
  Contains classes that applications use to programmatically gather information about network events, changes, statistics, and properties.

• System.Net.PeerToPeer
