Solution-level stylecop.json?

Hi. What if I want to use the same stylecop.json across all projects in the solution?
I’ve tried to make solution folder, put there stylecop.json and add it as a link to every project, but quick action “Add file header” still uses default style cop settings (I’ve changed company name).

(Sorry, I can’t add “question” tag to the issue)

📝 If you use the name Directory.Build.props and place the file in a parent directory (e.g. Root/Source instead of Root/Source/Shared), the file will be automatically imported by MSBuild, removing the need to manually reference it. This is how dotnet/roslyn-sdk includes the file for everything below src/Tools/Microsoft.CodeAnalysis.Testing without needing to update all of the individual project files: https://github.com/dotnet/roslyn-sdk/blob/3e94c5fe1ee981a885c34e2e39383bc4420f2557/src/Tools/Microsoft.CodeAnalysis.Testing/Directory.Build.props#L50-L60

@kkorus, in addition to @sharwell’s answer. Finally I ended up with SharedProjectSettings.proj file (there are 250+ csproj in my sources). It’s MSBuild project file, and it includes stylecop.json, as well as ruleset and other msbuild stuff:

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <CodeAnalysisRuleSet>..\..\Shared\StyleCop.ruleset</CodeAnalysisRuleSet>    
  </PropertyGroup> 

  <ItemGroup>
    <AdditionalFiles Include="..\..\Shared\stylecop.json" Link="Properties\stylecop.json" />
  </ItemGroup>

  <!-- ... -->
</Project>

Particular csproj imports SharedProjectSettings.proj:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
  </PropertyGroup>

  <Import Project="..\..\Shared\SharedProjectSettings.proj" />

  <!-- ... -->
</Project>
