FsAutoComplete
The FsAutoComplete project (FSAC) provides a backend service for rich editing or intellisense features for editors. It implements the Language Server Protocol.
Currently, it is used by the following extensions:
And it can be used with the following editors, by simply installing FsAutoComplete directly:
dotnet tool install --global fsautocomplete
It is based on:
- FSharp.Compiler.Service for F# language info.
- Ionide.ProjInfo for project/solution management.
- FSharpLint for the linter feature.
- Fantomas for F# code formatting.

I want your help. No really, I do.
There might be a little voice inside that tells you you're not ready; that you need to do one more tutorial, or learn another framework, or write a few more blog posts before you can help me with this project.
I assure you, that's not the case.
And you don't just have to write code. You can help out by writing documentation, tests, or even by giving feedback about this work. (And yes, that includes giving feedback about the contribution guidelines.)
Thank you for contributing!

### Added
- [Go to definition navigates between signature and implementation files](https://github.com/ionide/FsAutoComplete/pull/1544) - Go to definition resolves to the declaration in the signature file when a symbol has one, and to the matching definition in the implementation file when the cursor is already on that signature declaration
- Fantomas now reports which Fantomas a folder resolved to and where it was found, and whether its daemon could be started, to the `Fantomas` log. Previously nothing told a tool resolved from the `PATH` apart from the version a repository pins.
- Settings in the resolved Fantomas configuration that Fantomas could not act on - a `fsharp_` setting it does not have, or one carrying a value it cannot parse - are logged and shown once per file, naming the Fantomas version that could not act on them and offering to open the `.editorconfig` files involved and the file being formatted. Formatting still succeeds using defaults, so until now such a setting quietly did not apply. Only Fantomas 8 daemons report these.
### Changed
- ENHANCEMENT [Update analyzer package versions](https://github.com/ionide/FsAutoComplete/pull/1542) - Update the analyzer and project-system packages for FSharp.Core 10.1 and FCS 43.12 compatibility.
- Update `Fantomas.Client` to `0.12.0-beta-002`. Checkout the [changelog](https://github.com/fsprojects/fantomas/blob/main/src/Fantomas.Client/CHANGELOG.md) for more details.
### Fixed
- The Fantomas daemons FSAC starts are now shut down with the language server. The service owning them was never disposed, so every `fantomas daemon` process FSAC launched outlived the session that launched it.
- Fantomas failures other than a formatting error now report the message Fantomas wrote instead of a dump of the response record. `DaemonCreationFailed` in particular carries the standard error of the daemon that would not start, which was previously discarded.
- A cancelled format request is no longer reported to the user as a formatting failure.
- [Disable inline values by default to restore pipeline hints](https://github.com/ionide/FsAutoComplete/pull/1456) - `InlineValueProvider` is no longer advertised by default, restoring pipeline hints during normal editing (closes [#1214](https://github.com/ionide/FsAutoComplete/issues/1214))
