Hi everyone.
Just for fun, I created the RtMemoryCache, which is nothing more than a port of SysCache which uses System.Runtime.Caching.MemoryCache instead of System.Web.Caching.Cache.
WARNING: again, I did this just for fun. I made sure it passes all the unit tests (which are copied and modified from the SysCache ones), but I have never actually used it. I'm not responsible if it deletes your production data, burns down your datacenter, or kills your cat.

P.S. I don't usually read the nhusers group. Please reply in the nhibernate-development group if needed.
