I work in .NET on the daily on an M1 MBP using primarily VS Code and occasionally Rider.

There's no need for VS for most (any?) .NET workloads these days. That's why I wrote it was an early mis-step. Nowadays, it's easy to do .NET dev on any platform. In fact, we ship our production runtime to AWS t4g (Arm64) instances.

I primarily use JetBrains Rider for my daily tasks, and I agree that while you can use VS Code or even Vim with LSP support for many projects, working with substantial ones such as the runtime or ASP.NET Core development might practically necessitate using Visual Studio. By the way, the Visual Studio Community Edition is available for free for virtually all projects I can think of, mainly for personal, non-commercial, or open-source usage. The license details can be somewhat unclear, but that's my understanding of it.

The debugger is night and day vs visual studio. Not even comparable. Like 1% vs 99%. And there’s other tooling.

It can be done, but it’s so inferior to VS that you might as well use VS.
