Er, what? The VS Code extension gets updated all the time, it was updated in tandem with .NET through to .NET 6 and is currently being developed for .NET 7.
Works with
Linux x64, Alpine Linux 64 bit, macOS Intel, Linux ARM64, macOS Apple Silicon, Alpine Linux ARM64, Windows ARM, Windows ia32, Windows x64
.NET 6 is the first where they fully supported M1 Macs, maybe you last looked before .NET 6 released? Either way, VS Code is definitely a supported way to work with .NET.
