Adding Support for Fsharp

[SebastianAtWork]

Context

Would it be acceptable for me to add Support for FSharp inside vscode and rider? I would look into how the csharp support was made and would try to replicate that with FSharp. But before I put any time into that, I first want your accepted Tag so that an eventual PR is accepted :) Also any help and pointers about where to start would be appreciated.

Goals

Speech to FSharp Code

Proposed Solution

Language Support
