A list of tags to associate with the object.

Return Value

Type: Microsoft.ApplicationServer.Caching.DataCacheItemVersion

A DataCacheItemVersion object that represents the version of the object saved to the cache under the key value.

By passing the oldVersion parameter, this method can maintain concurrency. If another process updates the cached object before this method is called, this method does not update the cached object and returns null.

This overload is useful for updating the tags associated with the object.
