Looks good. Is there a linting tool for this?

dotnet-format is a code formatter for dotnet that applies style preferences to a project or solution. Preferences will be read from an .editorconfig file, if present, otherwise a default set of preferences will be used. At this time dotnet-format is able to format C# and Visual Basic projects with a subset of supported .editorconfig options.

Hmm, it isn't working on my machine, does it need Windows?
Can we add a linting job to our CI like we have in other languages?

[nvborisenko]

It doesn't require Windows.

Many things, which are supposed to work, don't work on this solution out of the box...

What did you have to do to get it working?
