Specifies the parameters required for a method to be invoked by a failure notification when the cache client misses cache notifications. Not supported in Windows Azure Shared Caching.
Assembly: Microsoft.ApplicationServer.Caching.Client (in Microsoft.ApplicationServer.Caching.Client.dll)
Public Delegate Sub DataCacheFailureNotificationCallback ( cacheName As String, nd As DataCacheNotificationDescriptor )
The name of the cache associated with the missing notifications.
The DataCacheNotificationDescriptor object associated with the failure notification that invoked the delegate method.
Failure notifications are triggered when the cache client misses one or more notifications. Similar to adding callbacks for cache notifications, adding a failure notification callback involves two steps. First, create a method that will be invoked when a failure notification is triggered. The method you invoke with the failure notification must accept the same parameters as this delegate. Second, add the failure notification callback using the AddFailureNotificationCallback method.
In order for your application to use notifications, you need to enable them on a named cache. In Microsoft AppFabric 1.1 for Windows Server Caching, use the notificationsEnabled parameter with the New-Cache or Set-CacheConfig Windows PowerShell commands. In Windows Azure Caching, enable notifications in the Caching configuration of the role that hosts the cache.
