Because it takes time. Even with coding agents, to add the capability. Then, there is the question on whether Rust developers who like to engage with Microsoft tools, would really consider Visual Studio as their IDE, instead of something like VS Code, VS Code Agent Mode, GitHub Copilot App, or GitHub Copilot CLI with simpler editors.

I'd be curious to know whether Rust developers believe Visual Studio is the right place for Microsoft to invest Rust specific coding capabilities.

Microsoft doesn’t use Visual Studio internally for many of its products such as Windows.

Given how long it took visual studio to get 64bit support, I wouldn't hold your breath!

( Edit: I should probably inform the layperson: It was Visual Studio 2022 )

It's only tier-1 for internal Microsoft use.

And for all we know, it might be officially supported in their internal builds of Visual Studio.

Because it is already supported in VS Code.

I don't think this is a hot take, but I'm predicting Microsoft will gradually phase out Visual Studio in favor of VS Code.

It is, with extensions (using rust-analyzer of course). I don't know what's the status inside Microsoft.
