## Health v2 (maintenance only)
Score: 10/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 5743, "days_push": 1396, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, archived
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
The historical repository for alternative packagings of the F# compiler, F# Interactive (fsi), and FSharp.Core, distributed via the FSharp.Compiler.Tools NuGet package and Debian packages. Development of the F# compiler has fully moved to dotnet/fsharp, so this repository is archival.

## Use cases
- install the F# compiler and F# interactive without Visual Studio
- override the in-box F# compiler in a .NET project via NuGet
- build F# code on Linux or Mono with fsc and fsi
- find where F# compiler development lives now
- package F# tools for Debian-based Linux distributions

## When to choose
- you need the archived FSharp.Compiler.Tools NuGet package or historical Debian packaging of F#
- you are researching the history or packaging of the F# toolchain

## When to avoid
- you want to contribute to or use the current F# compiler - use dotnet/fsharp instead
- you need a modern, actively maintained F# toolchain
- you are starting a new F# project

## Facets
- artifact type: library
- maturity: abandoned
- function: compiler, interpreter, programming-language, build-tool, sdk
- domain: programming-languages, compilers, developer-tools, cross-platform
- platform: cross-platform, windows, dotnet, cli
- tags: fsharp, fsharp-compiler, fsharp-interactive, nuget-packaging, debian-packaging, archived, compiler-tools, linux, macos, mono
