DotNetRemoting framework does not rely upon the events (or callbacks). It createsbidirectional channel on the top of the socket. All the classes in the hierarchy are derived from the base class that holdsthe socket. This approach makes the asynchronous call as the most appropriate, alsoIt allows to make the communication behind the firewall possible. The port has to beopened on the firewall. If your NAT or firewall supports socks 4(5) protocol,You may connect your client through ProxyConnector component.You need DotNetRemoting if *You need a quick solution and you do not want to spend your time on connections,activations, threads synchronization and firewall transparency. The framework takescare of everything *You want bidirectional communication. *If need a top performance. *Communication with mobile devices (Pocket PC, smartphones) *You need GPRS comms channel on your PDA*Encryption*Firewall transparency *Easy deployment Synchronous vs. Asynchronous Calling the methods in standard .Net remoting is always synchronous process bydefinition. In other words you always have to wait for the completeion of the call.That is how any standard call of any method works. It is good for short operations,but what if the operation is lengthy? What if the server is doing intensive andlengthy database search? Your application is frozen until the call returns. DNRsupports two models at once - synchronous and asynchronous. You can use RMI/RPC forsynchronous calls - like in traditional .Net remoting. Or you can use asynchronousWhen the response comes, it invokes method on your class and most importantly itinvokes it in the main thread. Why is it so crucial that it invokes the method inthe main thread? It is essential because any attempt to invoke GUI method from theworker (not main) thread at best will crash your application, at worst the behaviorof your application will become unpredictable.
