System.Configuration ClientConfigPaths constructor; Operation is not supported on this platform

I'm trying to memoize a function using System.Runtime.Caching.MemoryCache, but calling MemoryCache's constructor gives the following error:

 PlatformNotSupportedException: Operation is not supported on this platform.

It seems to have something to do with the ClientConfigPaths constructor, but I can't figure out if this is just an incompatibility between ClientConfigPaths and Unity, or if it's something fixable.
