I've been using it exclusively on an M1 Mac for the last 2+ years. I was just at a startup where the entire team was deploying into T4 Arm instances in AWS. Two developers started on Windows machines, but at the end, every developer was on a Mac.

I have some workloads that I'm developing on my M1 Mac that I'm containerizing and pushing into an x64 Linux runtime environment in Google Cloud.

I guess this is my point: a lot of misunderstanding and misconception about the state of C# and .NET.
