is there a thick client equivalant to HttpContext.Current.Cache and SqlCacheDependency?

[PJ6]

I have a thick client application with lookup lists that I want to
automatically update much in the same way they can be in a web application
using HttpContext.Cur rent.Cache. I don't want to re-invent the wheel, here
(I rolled my own, years ago), I want to use something that's already
built-in, or do it in a way that's been tested and established as "best
practice" for a 2-teir thick client model. Any pointers?

Thanks,
Paul
