@LyalinDotCom:Thanks Lyalin. That's what I expected to happen but thats is not the case. I don't see the references (or any CodeLens at all) in my project. What do I have to do to enable it? I even created a new project from the scratch and no CodeLens are been displayed.
Is CodeLens an Ultimate only feature or it is available in the Premium version?
UPDATE: I've just installed the Ultimate Preview version and the CodeLens is now working. So I assume it is an Ultimate only feature (It was not clear in the video). That's is not very good since in my workplace we only have the Premium version. The references were one of the biggest reason to upgrade our environment to VS2013. We have about 40 licenses and upgrade all to Ultimate would not be cost viable. I think Microsoft should consider include that feature in the other "flavors" of VS2013.
