System.Runtime.Remoting.Channels.Ipc

Defines a communication channel for remoting that uses the Interprocess Communication (IPC) system of the Windows operating system.

Multiple objects can live inside a context.

System.Runtime.Remoting.Lifetime

Contains classes that manage the lifetime of remote objects. Traditionally, distributed garbage collection uses reference counts and pinging for control over the lifetime of objects. This works well when there are a few clients per service, but does not scale well to thousands of clients per service. The remoting lifetime service associates a lease with each service, and deletes a service when its lease time expires. The lifetime service can take on the function of a traditional distributed garbage collector, and it also adjusts well when the numbers of clients per server increases.

System.Runtime.Remoting.Messaging

Contains classes used to create and remote messages. The remoting infrastructure uses messages to communicate with remote objects. Messages are used to transmit remote method calls, to activate remote objects, and to communicate information. A message object carries a set of named properties, including action identifiers, envoy information, and parameters.
