Missing CodeLens references count in Visual Studio Community edition 2015 and 2017

Question

1. Is there a reason why the references count (code lens) is missing in Visual Studio Community edition?
2. Is is possible to enable it in the options?

Answer 1

I installed the latest SSDT preview for Visual Studio 2015 from the link below on 2 machines I have with VS 2015 Community edition (Update 1), and CodeLens started working for all my projects.
