There's two ways to approach this — build tooling for existing Rust developers to get them to adopt the Microsoft stack, or build tooling for existing Microsoft stack developers to get them to adopt Rust.
I'd argue that the former is less important than the latter, and my understanding is that Visual Studio is still the IDE for Windows-centric development, so for those MS-first developers, Rust missing from VS means Rust is poorly supported, end of story.
