Even reflection is going to vary based on your IDE. If you use ReSharper or Rider, a safe rename refactoring will locate and optionally update string references as well. I don't know if VS itself has adopted this feature.

IDEA does the same thing. It's amazingly useful, even if you don't use reflection -- variable names end up in comments and documentation as well, all of which it will offer to change.

I’ve never touched a “real life” code base in a static language (including C#) where this wouldn’t be an issue. C# is not a sufficiently high level language that I can avoid duplication without the use of reflection.
