This topic is specific to a legacy technology that is retained for backward compatibility with existing applications and is not recommended for new development. Distributed applications should now be developed using the Windows Communication Foundation (WCF).
Contains channels that the application uses to communicate with remote objects. This element configures channel templates or declares new channels for use with the specified application. This element may occur in an application configuration file, machine configuration file.
