For C# Rider has had superior tooling for debugging for years now.

OK, maybe my point got lost because I didn't know that, but I should have just added Visual Studio to my list — it too has LLM and agentic features, which was my point.

If you can't use LLMs to generate placeholder graphics that don't ship in the actual game, then why can you use coding editors that let you use LLMs to generate code?
