Gets the application extension services that have been registered for this application.
Public ReadOnly Property ApplicationLifetimeObjects As IList Get
Dim instance As Application Dim value As IList value = instance.ApplicationLifetimeObjects
public IList ApplicationLifetimeObjects { get; }
<Application> <Application.ApplicationLifetimeObjects> oneOrMoreServiceElements </Application.ApplicationLifetimeObjects> </Application>
One or more object elements, each of which creates and defines an IApplicationService instance. Each element requires an XML namespace prefix mapped to the namespace and assembly where the service is defined.
Application extension services provide a way to extend the Silverlight application model without requiring specialized Application subclasses. Applications can continue to inherit the Application class directly, and can add extensions by populating the ApplicationLifetimeObjects list. Applications can do this in the class constructor or in the application XAML.
Application extension services implement the IApplicationService interface and optionally the IApplicationLifetimeAware interface. These interfaces define access points to the application lifetime events.
The order of the services in the ApplicationLifetimeObjects list dictates the order in which the services are initialized. This is also the order in which the services receive application lifetime event notifications. The services are shut down in the opposite order. The guaranteed ordering enables services to fulfill complex dependencies in the application and in other services.
