Syntax

public DataCacheNotificationDescriptor AddFailureNotificationCallback(
    DataCacheFailureNotificationCallback failureCallback
)

public:
DataCacheNotificationDescriptor^ AddFailureNotificationCallback(
    DataCacheFailureNotificationCallback^ failureCallback
)

member AddFailureNotificationCallback : 
        failureCallback:DataCacheFailureNotificationCallback -> DataCacheNotificationDescriptor

Public Function AddFailureNotificationCallback (
    failureCallback As DataCacheFailureNotificationCallback
) As DataCacheNotificationDescriptor

Parameters

Return Value

Type: Microsoft.ApplicationServer.Caching.DataCacheNotificationDescriptor

A DataCacheNotificationDescriptor object used to identify the cache notification callback.

Remarks

The failureCallback method you invoke with the failure notification must accept the same parameters as the DataCacheFailureNotificationCallback delegate.

Note

In order for your application to use notifications, you need to enable them on a named cache. For Windows Server AppFabric Caching, use the NotificationsEnabled parameter with the New-Cache or Set-CacheConfig Windows PowerShell commands. For Windows Azure Caching on roles, enable notifications in the cache settings.
