Remarks

Server-activated object types can be either single call or singleton. If an object type is single call, a new instance of it is created each time a call from the client comes in. All calls to a singleton object are handled by one instance of that object.

Any client that knows the URI of this object can obtain a proxy for this object by registering the channel it prefers with ChannelServices and activating the object by calling new or Activator.GetObject.

It is important to note that the remote object itself is not created by the registration process. This only happens when a client attempts to call a method on the object or activates the object from the client side.

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