There are several artifacts involved in the development of F#:
* The [F# compiler library](https://github.com/dotnet/fsharp/tree/master/src/fsharp/FSharp.Compiler.Private), called `FSharp.Compiler.Private`. Contains all logic for F# compilation - including parsing, syntax tree processing, typechecking, constraint solving, optimizations, IL importing, IL writing, pretty printing of F# constructs, and F# metadata format processing - and the F# compiler APIs for tooling.
* The [F# compiler library](https://github.com/dotnet/fsharp/tree/master/src/fsharp/FSharp.Compiler.Service), called `FSharp.Compiler.Service`. Contains all logic for F# compilation - including parsing, syntax tree processing, typechecking, constraint solving, optimizations, IL importing, IL writing, pretty printing of F# constructs, and F# metadata format processing - and the F# compiler APIs for tooling.
* The [F# compiler executable](https://github.com/dotnet/fsharp/tree/master/src/fsharp/fsc), called `fsc`, which is called as a console app. It sets the .NET GC into batch mode and then invokes `FSharp.Compiler.Private` with command-line arguments.

* The [F# Core Library](https://github.com/dotnet/fsharp/tree/master/src/fsharp/FSharp.Core), called `FSharp.Core`. Contains all primitive F# types and logic for how they interact, core data structures and library functions for operating on them, structured printing logic, units of measure for scientific programming, core numeric functionality, F# quotations, F# type reflection logic, and asynchronous programming types and logic.

* The [F# Interactive tool](https://github.com/dotnet/fsharp/tree/master/src/fsharp/fsi), called `fsi`. A REPL for F# that supports execution and pretty-printing of F# code and results, loading F# script files, referencing assemblies, and referencing packages from NuGet.

* The [F# Compiler Service](https://github.com/dotnet/fsharp/tree/master/fcs), called `FSharp.Compiler.Service` or abbreviated to FCS. It is mostly identical to `FSharp.Compiler.Private`, but critically contains the "Expression API" that allows other environments to inspect and operate on type-checked F# expressions (such as transpiling F# code to a different runtime target).
The `FSharp.Compiler.Service` is by far the largest of these components and contains nearly all logic that `fsc` and `fsi` use. It is the primary subject of this guide.
