问题
according to msdn System.runtime.caching is not available to the client profile. currently this caching works for .net full. where my application is going to be deployed only supports the client profile so retargeting is not a option. is there a open source library that will implement this functionality / or would it be better to download system.runtime.caching project from http://referencesource.microsoft.com/#System.Runtime.Caching/System/Caching and attempt to re implement the classes removing dependency's from the full framework is this even possible ?.
