The version of the cached object.
Assembly: Microsoft.ApplicationServer.Caching.Core (in Microsoft.ApplicationServer.Caching.Core.dll)
The DataCacheItemVersion is updated every time the object is updated. Only the latest version of the object is stored on the cache cluster. Due to the distributed nature of the cluster, the cache client may not have the latest copy of the object. For this reason, the DataCacheItemVersion class is essential for concurrency operations.
When using cache notifications, the DataCacheItemVersion object corresponding to an item-related cache operation can be returned to your application with the version parameter of the DataCacheNotificationCallback delegate method.
Notifications are not supported in Windows Azure Shared Caching.
