Just a heads-up this morning ... I needed a lightweight caching library (not EntLib) so I went searching for one, hoping that some kind developer had published one of acceptable quality. After bumbling around for 10 minutes I discover that the System.Runtime.Caching <http://msdn.microsoft.com/en-us/library/system.runtime.caching.aspx> namespace was under my nose and I missed it. Well, it looks like it only snuck in with Framework 4, so I guess it was easy to miss.
I haven't tried yet, but it seems to have everything you'd expect, like callbacks, policies, and extensibility. I get the impression it only has a memory cache implementation (but I see "monitor" classes for files and SQL Server?). I expect to give it a bash over the coming weeks and I'll let you know what I find, unless someone has already given it a good go and can give it thumbs up or down. Greg
