What are the consideration in deciding to use .NET Remoting or ASP.NET Web Services

Remoting is a more efficient communication exchange when you can control both ends of the application involved in the communication process. Web Services provide an open-protocol-based exchange of informaion. Web Services are best when you need to communicate with an external organization or another (non-.NET) technology.

Hi,
.NET remoting is replacement of DCOM. Using .NET remoting you can make remoteobject calls which lie in different Application Domains. As the remote objects run indifferent process client calling the remote object can not call it directly. So the client usesa proxy which looks like a real object.When client wants to make method call on the remote object it uses proxy for it. Thesemethod calls are called as “Messages”. Messages are serialized using “formatter” classand sent to client “channel”. Client Channel communicates with Server Channel. ServerChannel uses as formatter to deserialize the message and sends to the remote object.

All remote object should inherit from System.MarshallbyRefObject.


There are two different ways in which object can be created using Remoting :-
SAO (Server Activated Objects) also called as Well-Known call mode.

√CAO (Client Activated Objects)

SAO has two modes “Single Call” and “Singleton”. With Single Call object the object iscreated with every method call thus making the object stateless. With Singleton the objectis created only once and the object is shared with all clients.
CAO are stateful as compared to SAO.In CAO the creation request is sent from clientside. Client holds a proxy to the server object created on server..


Hope u get cleared about .Net Remoting
