Client-activated objects - A client-activated object is a server-side object whose creation and destruction is controlled by the client application. An instance of the remote object is created when the client calls the new operator on the server object. This instance lives as long as the client needs it, and lives across one to many method calls. The object will be subject to garbage collection once it's determined that no other clients need it. Server-activated objects - A server-activated object's lifetime is managed by the remote server, not the client that instantiates the object. This differs from the client-activated object, where the client governs when the object will be marked for finalization. It is important to understand that the server-activated objects are not created when a client calls New or Activator.GetObject. They are rather created when the client actually invokes a method on the proxy. There are two types of server activated objects. They are: Single call . Single-call objects handle one, and only one, request coming from a client. When the client calls a method on a single call object, the object constructs itself, performs whatever action the method calls for, and the object is then subject to garbage collection. No state is held between calls, and each call (no matter what client it came from) is called on a new object instance. Singleton - The difference in a singleton and single call lies in lifetime management. While single-call objects are stateless in nature, singletons are stateful objects, meaning that they can be used to retain state across multiple method calls. A singleton object instance serves multiple clients, allowing those clients to share data among themselves. A Look At ASP.NET Web Services With the arrival of .NET, creating an ASP.NET Web service is a breezy experience with the .NET framework taking away all the complexities in creating and consuming Web services. To create a Web service, all you need to do is create a Web service class that derives from the System.Web.Services.WebService class and decorate the methods (that you want to expose as Web services) with the WebMethod attribute. Once this is done, these methods can be invoked by sending HTTP requests using SOAP. Consuming a Web service is very straightforward too. You can very easily create a proxy class for your Web service using either wsdl.exe utility or the Add Web Reference option in VS.NET. The Web service proxy hides all the network and marshaling plumbing from the application code, so using the Web service looks just like using any other local object. Click here for larger image As you can see from the above diagram, the client proxy receives the request from the client, serializes the request into a SOAP request which is then forwarded to the remote Web service. The remote Web service receives the SOAP request, executes the method, and sends the results in the form of a SOAP response to the client proxy, which deserializes the message and forwards the actual results to the client.
