You can look into the Caching Application Microsoft has published. This is a generic implementation that can be used in the middle tier and in WinForm apps.

Caching can be a huge win if you do it correctly, and I've been thinking alot (but not doing it) about how to best implement it in my middle tier. Currently I have all of my lists in Web apps cached and this works really well and has eliminated backend data access on a quarter of the app to nothing which results in significant performance gains...

FWIW, I'm not aware that you can't instantiate a Cache object of your own... I think you can, but only one instance can exist per AppDomain which means the model would be different between WinForms and Web Apps as Web apps automatically provide an instance on the HttpContext object.
