Setting the properties for a new application in the Internet Information Services (IIS)ManagerIf you did everything correctly, your service is reachable through IIS 7.0. You can testthis by navigating to your newly created application, for example: http://localhost:8080/QuickReturns/Exchange.svc/ExchangeService.Windows Activation ServicesWAS enables you to host any WCF service, supporting any transport inside the IIS model. WAStakes over creating worker processes and providing the configuration from the original W3svc.exe Windows service that you know from IIS 6.0 (and runs inside the Inetinfo.exe process).WAS and IIS now share the configuration store that defines sites, applications, applicationpools, and virtual directories. In this section, we’ll walk you through the process of activationwith WAS, as shown in Figure 5-16.By default when no requests are being made to a newly booted server, Windows runs fiveservices (if all the protocols are enabled). These are the following Windows services:• WAS• World Wide Web Publishing Service (hosting the listener adapter)• NET.TCP listener adapterramrameshreddyramrameshreddy• NET.PIPE listener adapter• NET.MSMQ listener adapterWhen the listener adapters start, they register themselves with WAS and receive the WAS/IISconfiguration for their specific protocols. In this way, the listener adapters are aware of the sitesand applications they should support. Each listener adapter then starts listening on the appropriateports provided with the configuration so it can dispatch the requests coming in to theappropriate application.
