Description

This issue has been moved from a ticket on Developer Community.

I have a few custom attributes defined in some of my projects. It looks like if they have an explicit constructor with some parameter, CodeLens correctly shows the references over the constructor as expected. But, if the attributes have no constructor and are just added with the standard [SomeAttribute] syntax, then I only see "0 references" over the attribute type definition, with no easy way to find the actual usages of that attribute in the project.

CodeLens should correctly report all the actual usages of the attribute in the current project, regardless of how they're defined and added to the respective targets in the codebase.

Contributor guide

Research direction
Investigate the CodeLens provider for attributes in the Roslyn codebase. Focus on how references are calculated for attribute types that do not have an explicit constructor. Trace the code path from the attribute usage to the reference count display.
