[SUGGESTION] Extract "Common Project System" related features, and make "CPS Core" extension from them.

Describe the feature you'd like

I love VSCode C# Dev Kit extension, and Project System / Solution Explorer feature of it.

But, the project system only support C# project.
It does not support my F# project.

I suppose C# Dev Kit is based on .NET Project System for Visual Studio, becase of this code.

And .NET Project System is based on Common Project System (CPS) framework.

According to VS Project System document, CPS is made up of two parts, 'CPS Core' and 'CPS VS',
and CPS Core is designed to be independent of VS. (for VSCode, maybe?)

So, I have 2 requests.

1. Make official VS Code Project System extension, based on CPS Core.
2. Provide official VS Code Project System Add-On Dev Tool for community.

Alternatives considered

1. Use Visual Studio, not VS Code.

VS Code is more lightweight and flexible.
And, Visual Studio not support Linux and OSX.
(I'm Window user, but I want to make my CPS Add-On, and deploy it to Linux or OSX users.)

2. Why 'official'? Open source community can make what you want.

The main library of CPS Core is closed source, proprietary software.
And no tutorial, no API reference documents.
In this situation, only 'official' can make what I want.

Environment Information

OS: Windows 10 Pro 19045.4412 (x64)
VS Code: 1.90.0
Extension: C# Dev Kit v1.6.8

Start by reviewing the linked CPS Core versus CPS VS overview and the referenced .NET Project System code. The requested outcome is an official VS Code Project System extension supporting F# and an official add-on development tool, but the issue names no repository entry points, files, or tests to run.
