Where I set the option in Visual Studio 2015 to show the Sub / Function reference, where they are being used.
(Ex: Function RecordData> I call it in the Save button), then on top of the Function the reference appears and shows where it was called. Here in my VS is gone.
This feature is called CodeLens. It can be enabled or disabled in Visual Studio settings (Tools -> Options).
Notethatthisfeatureisonlyavailableon Visual Studio Ultimate or Professional . This is one of the few things that Community does not have in relation to the Professional.
It may have had some extension that did this and it may have been disabled for some reason.
You can still find where it was used with Shift + F12 .
Resharper can help further.
