Both of these options can do this on a per solution, project, document basis.

If you want to this via command-line, look at dotnet format. These all work better if you’ve got a good .editorconfig that calls the style. You can have IntelliCode automatically generate one based on the project via Add -> New Item -> Editor Config (IntelliCode).

Subject: VS2022 format all files

Folks, is there a way to apply commands like Format Document and Remove and Sort Usings to multiple C# files, perhaps all open files or all files in the project?

Web searches suggest it's not possible at the moment. I see an Extension for this which looks a bit flakey and I won't try it yet.

Taking this even further, I occasionally need to "beautify" C# code in hundreds of files in projects to fix things like indentation, tabs, usings and more fiddly things like removing excess blank lines, putting gaps between methods, etc. That is, I want to bring code that is sometimes haphazardly formatted back to a vanilla format acceptable to typical developers.

Cheers,

Greg Keogh
