System.Runtime.Remoting Namespace


The System.Runtime.Remoting namespace provides classes and interfaces that allow developers to create and configure distributed applications. Some of the more important classes of the System.Runtime.Remoting namespace are the RemotingConfiguration class, the RemotingServices class, and the ObjRef class.


Holds values for an object type registered on the client end as a type that can be activated on the server.


Holds values for an object type registered on the service end as one that can be activated on request from a client.


Defines utility methods for use by the .NET Framework remoting infrastructure.


Wraps marshal-by-value object references, allowing them to be returned through an indirection.


Stores all relevant information required to generate a proxy in order to communicate with a remote object.


Provides various static methods for configuring the remoting infrastructure.


The exception that is thrown when something has gone wrong during remoting.


Provides several methods for using and publishing remoted objects and proxies. This class cannot be inherited.


The exception that is thrown when the server or the client cannot be reached for a previously specified period of time.


The exception that is thrown to communicate errors to the client when the client connects to non-.NET Framework applications that cannot throw exceptions.


Provides several methods for using and publishing remoted objects in SOAP format.


Implements a base class that holds the configuration information used to activate an instance of a remote type.


Holds values for an object type registered on the client as a server-activated type (single call or singleton).


Holds values for an object type registered on the service end as a server-activated type object (single call or singleton).


Provides custom channel information that is carried along with the ObjRef.


Provides envoy information.


Defines the interface for unwrapping marshal-by-value objects from indirection.


Provides type information for an object.


Specifies how custom errors are handled.


Defines how well-known objects are activated.

The RemotingConfiguration class contains static methods for interfacing with configuration settings. The RemotingConfiguration.Configure method allows developers to configure the remoting infrastructure through the use of XML formatted configuration files. The RemotingConfiguration class also contains several methods for client-end and server-end registration of client and server activated objects that reside on the server.

The RemotingServices class provides a number of methods to help in using and publishing remoted objects. The M:System.Runtime.Remoting.RemotingServices.Marshal method provides the functionality for storing all the relevant information required to activate and communicate with a remote object in an instance of the ObjRef class for later serialization and transmission to a remote location. The M:System.Runtime.Remoting.RemotingServices.Unmarshal method reverses this process, creating a proxy for a remote object that can be used by an application without regard for any remoting subdivisions.

The ObjRef class holds all the relevant information required to activate and communicate with a remote object. This class is a serializable representation of an object that is transmitted to a remote location using a channel, where it is unmarshaled (see M:System.Runtime.Remoting.RemotingServices.Unmarshal) and can be used to create a local proxy of the remoted object.


Marshal-by-reference objects (MBRs) do not reside in memory forever. Instead, unless the type overrides MarshalByRefObject.InitializeLifetimeService to control its own lifetime policies, each MBR has a finite lifetime before the .NET Framework remoting system begins the process of deleting it and reclaiming the memory.
