Is there a comprehensive C# linter and formatter like eslint for JS/TS?

I'd like to have my C# projects (.NET Core 3.1+) to be linted and formatted on each build both locally and in CI environment. I know that there's new .NET Analyzers feature and dotnet-format tool in .NET 6, but I can't understand from the documentation if I can make a single comprehensive configuration file that both these tools would use so I can enforce certain code style in my team. Could you help me understand if it is possible?

Yes there is - Roslyn Analyzers.

With a EnforceCodeStyleInBuild element set in your .csproj:

 <PropertyGroup><TargetFramework>net6.0</TargetFramework><Nullable>enable</Nullable><ImplicitUsings>enable</ImplicitUsings><!-- this! --><EnforceCodeStyleInBuild>true</EnforceCodeStyleInBuild></PropertyGroup>

an .editorconfig file in your project, which you can get like this:

dotnet new editorconfig

and updating your VS Code settings.json to include:

{"omnisharp.enableRoslynAnalyzers": true,"omnisharp.enableEditorConfigSupport": true}

And you should be off to the races! I've written this up in more depth here:
