This folder contains projects and tests related to Visual Studio tooling.

Top-level project for the Visual F# IDE tools. This project contains the following

• Interfaces which implement Roslyn workspace APIs
• Top-level interactions with the F# Compiler Service
• Logic for handling data in the F# Compiler Service
• Helpers for interacting with Roslyn APIs
• Various utilities

In general, if something is implemented here and the logic becomes rather lengthy, it may be a good idea to push that logic down into the F# Compiler Service so that other editors can benefit.

F# Interactive implementation.

GUI controls and resources for Visual F# tooling.

Legacy bindings to the F# Compiler Service. Most of the code paths here are dead, and exist mainly to allow our test suite to extensively test the F# Compiler Service.

Legacy bits for a base-level, editor-agnostic language service. This code isn't used anywhere else, though.

Legacy bindings to the legacy (and unsupported) MPF project system type in Visual Studio. This code will eventually be deprecated.

Legacy project system to handle F# projects targeting the .NET Framework, with some code paths also handling .NET Core. The latter will eventually be factored out, as this code will eventually be deprecated.

GUI for F# project properties.

Legacy tooling for IDE unit tests. Used extensively in tests, hence it still exists.

IDE unit tests. Some code paths go through bits which aren't ever executed when using F# in Visual Studio, but they do extensively test the F# Compiler Service.

A skeleton command line tool which exercises the F# Compiler Service.

Visual Studio item templates for F# projects.

Visual Studio project templates for .NET Framework projects.
