Somehow CodeLens doesn't work correctly. It only shows -references. It was working fine before.
I checked the Options -> Text Editor -> All Language -> CodeLens
All options are checked.
Anyone see this before ? Thanks
update: It is fixed after I upgrade to vs2015 update 1 RC1
It turns out it is conflicted with another extension I installed called "Go To Implementation".
It happens again. This time I have no clue. Anyone ?
