I followed the guide here:

http://www.windowsazure.com/en-us/develop/net/how-to-guides/cache/

exactly and my cache is working as expected I am able to store and retrieve data so why has the achievement not shown up?  The azure account I am connecting to is my companies and has been around for a while.  I'm assuming there is something in VS that should be triggering this but it is not.  Thanks.
