There is a new extension in the gallery for Visual Studio 2022 support.
The original release in the gallery supports Visual Studio 2019 and Visual Studio 2017.
(There is a bug where Visual Studio will reset some settings on upgrade.)
See Indent Guides in the Visual Studio Gallery for the latest stable release and end-user QA.
The screenshots are from Indent Guides v13, which looks the same as v17 but has more bugs :)
