Question

I\'ve got a simple object being cached like this:

_myCache.Add(someKey, someObj, policy);

There's a property on the CacheItemPolicy called RemovedCallback which is of type: CacheEntryRemovedCallback. Not sure why they didn't go the standard event route, but that should do what you need.
