Remarks

The current class is used by the RemotingConfiguration.RegisterActivatedServiceType method, which is the server-side counterpart of the RemotingConfiguration.RegisterActivatedClientType method. The RegisterActivatedServiceType method is used on the server to allow remote activation by clients of specified object types.

To create a client-activated object on the server, you must know its Type, and it must be registered on the server end by using the RegisterActivatedServiceType method. To obtain a proxy for a new client-activated object, the client must first register a channel with ChannelServices and then activate the object by calling new or Activator.CreateInstance.

To activate a client-activated object type with the new keyword, you must first register the object type on the client using the RegisterActivatedClientType method. By calling RegisterActivatedClientType you are giving the remoting infrastructure the location of the remote application where new attempts to create it. If, on the other hand, you use the CreateInstance method to create a new instance of the client-activated object, you must supply the remote application's URL as a parameter, so no prior registration on the client is necessary. To supply the CreateInstance method with the URL of the server on which you want to create the object, you must encapsulate the URL in an instance of the UrlAttribute class.

For a detailed description of client-activated objects and remote object activation, see Activation of Remote Objects.
