Defines a reference to a method that is invoked when a cache entry is about to be removed from the cache.
Assembly: System.Runtime.Caching (in System.Runtime.Caching.dll)
Information about a cache entry to be removed is contained in a CacheEntryUpdateArguments object. A CacheEntryUpdateArguments object is passed to the delegate. The method that implements the delegate can pass an updated cache entry value back to the cache implementation. The updated cache entry replaces the cache item that is about to be removed.
