What is .net Remoting (  version 1.1. and 2.0)

.NET Remoting is a mechanism for communicating between objects which are not in the same process. It is a generic system for different applications to communicate with one another. .NET objects are exposed to remote processes, thus allowing inter process communication. The applications can be located on the same computer, different computers on the same network, or on computers across separate networks.

Microsoft .NET Remoting provides a framework that allows objects to interact with each other across application domains. Remoting was designed in such a way that it hides the most difficult aspects like managing connections, marshaling data, and reading and writing XML and SOAP. The framework provides a number of services, including object activation and object lifetime support, as well as communication channels which are responsible for transporting messages to and from remote applications.

.NET remoting enables you to build widely distributed applications easily, whether application components are all on one computer or spread out across the entire world. You can build client applications that use objects in other processes on the same computer or on any other computer that is reachable over its network. You can also use .NET remoting to communicate with other application domains in the same process. (For details about programming application domains, see Programming with Application Domains.)

.NET remoting provides an abstract approach to interprocess communication that separates the remotable object from a specific client or server application domain and from a specific mechanism of communication. As a result, it is flexible and easily customizable. You can replace one communication protocol with another, or one serialization format with another without recompiling the client or the server. In addition, the remoting system assumes no particular application model. You can communicate from a Web application, a console application, a Windows Service – from almost anything you want to use. Remoting servers can also be any type of application domain. Any application can host remoting objects and provide its services to any client on its computer or network.

To use .NET remoting to build an application in which two components communicate directly across an application domain boundary, you need to build only the following:

• A remotable object.
• A host application domain to listen for requests for that object.
• A client application domain that makes requests for that object.

Even in a complex, multiclient/multiserver application, .NET remoting can be thought of in this way. The host and the client application must also be configured with the remoting infrastructure and you must understand the lifetime and activation issues that the remoting infrastructure introduces.
