title: Is there a in memory cache for portable class library?
body: <p>I'm build an app that needs some sort of caching, and since my models and viewmodels live in the portable class library i want some sort of caching there too... but PCL is limited, and I cant seem to find any. </p>
  
  <p>I would like to use System.Runtime.Caching but thats not included in the PCL - is there any other options?</p>
