The .NET Framework is a modern platform for building distributed applications. In this chapter, you learned how to create distributed applications using the remoting library of the .NET Framework.

KEY TERMS

• Application domain

• Asynchronous call

• Channel

• Marshalling

• Proxy

• Synchronous call

• Remoting

• Runtime Host

You learned that the remoting framework is made up of several elements such as a remotable class, remoting host, remoting client, channel, formatters, and so on. Each of these elements is configurable and extensible. You practiced creating a remotable class and hosting that in several modes such as server-activated SingleCall, server-activated Singleton, and client-activated objects. You also used different channels, such as HTTP and TCP, and different formatters, such as SOAP and binary.

I also demonstrated the use of a configuration file to configure remoting for a remoting host and a remoting client. You noted that depending on your requirements, you can save the remoting configuration at two levels ‚ one at the application level (.exe.config, .dll.config, or web.config for IIS) and the other at machine-level (machine.config).

Finally, I discussed the technique of invoking a remote method asynchronously with the help of delegates. An asynchronous method class makes a user -interface ‚ based application, such as a Windows forms application, quite responsive to user input despite the delays caused in a remote method call.
