Is there some sort of CacheDependency in System.Ru

问题:

I heard that .NET 4 has a new caching API.

Okay, so the good old System.Web.Caching.Cache (which is, by the way, still there in .NET 4) has the ability to set so-called CacheDependency objects to determine whether a cached item is expired or not.

One can also specify custom logic for determining whether a cached item is still useable or not by deriving a custom subclass from CacheDependency.

I'm curious, is there a way to provide such a logic in the new API?

回答1:

I haven't really used it yet but classes derived from ChangeMonitor Class appear to serve a similar purpose.
