In CAO model for client objects to be created by “NEW” keyword what should we do?

Remoting Clients and Remoting Server can communicate because they share a common contract by implementing Shared Interface or Base Class (As seen in previous examples). But according to OOP’s concept we can not create a object of interface or Base Classes (Abstract Class). Shipping the server object to client is not a good design practice. In CAO model we can use SOAPSUDS utility to generate Metadata DLL from server which can be shipped to client, clients can then use this DLL for creating object on server. Run the

In application domains multiple applications can run in same process with out influencing each other. If one of the application domains throws error it does not affect the other application domains.
