This class provides configuration and management functionality for application pools. Properties of this class generally correspond directly to the attributes of the applicationPools configuration element in the IIS 7 configuration system.
Application pools are associated with worker processes, contain one or more applications, and provide isolation among different applications.
The following example implements several of the methods and properties of the ApplicationPool class. This example retrieves the ApplicationPool objects in the service module, modifies the property values of the ApplicationPool objects, places the objects into a property bag, and displays the property values in the page module.
