With a statically typed language like C# or Java, there are dozens of refactors that IDEs could do in a guaranteed [1] correct way better than LLMs as far back as 2012. The canonical products were from JetBrains. I haven’t used Jetbrains in years. But I would be really surprised with the combination of LLMs + a complete understanding of the codebase through static analysis (like it was doing well over a decade ago) and calling a “refactor tool” that it wouldn’t have better results. [1] before I get “well actuallied” yes I know if you use reflection all bets are off.
