<channels> Element (Instance)

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.

The following configuration file declares the location of a remote type for a client application and uses the <channels> instance element to specify to the .NET Framework remoting system that it should locate an appropriate port from which to connect to the server object, and that it should use the default HttpChannel.

<configuration>
   <system.runtime.remoting>
      <application>
         <client>
            <wellknown 
               type="RemoteType, RemoteAssembly"
               url="http://computername:8080/RemoteType.rem"
            />
         </client>
         <channels>
            <channel 
               ref="http"
