You did not. Aside from Rust and Swift, all the added languages are preliminary. A minimal extension is required to, for example, connect Chime up to an LSP server to get semantic features going like completions and diagnostics. We do not have a 1st-party extension built for C# yet.
That's more or less exactly what we've done. Our SDK does have support for LSP. But, unfortunately those extensions still need to be made. Or are you talking about a generic LSP extension that is server-agnostic? That is definitely buildable, but my experience has been that the experience tends to be a lot better when customized for a particular server.
