How to get a stylecop ruleset trough nuget in a .net standard project

Question

We are trying to provide a nuget package for all our projects with a stylecop ruleset. We get the files in the project but the ruleset is not applied to our projects. It still uses the minimimumrecomended.ruleset.

what we have now is:

Custom.stylecop.props

<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <RunCodeAnalysis>true</RunCodeAnalysis>
    <CodeAnalysisRuleSet>Custom.StyleCop.ruleset</CodeAnalysisRuleSet>
  </PropertyGroup>
</Project>

custom.stylecop.targets

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ItemGroup>
    <AdditionalFiles Include="$(MSBuildThisFileDirectory)\Content\stylecop.json">
      <Link>stylecop.json</Link>
    </AdditionalFiles>
  </ItemGroup>
</Project>

Custom.stylecop.nuspec

<contentFiles>
    <files include="Content/stylecop.json" buildAction="EmbeddedResource" />
</contentFiles>
....
<files>
    <file src="build\**" target="build" />
    <file src="Content/stylecop.json" target="contentFiles" />
</files>

Does anyone have any idee or an example on github or so where we can find an example because we could not find any.

Answer 1

We solved the issue with the following:

CodeAnalysis.props

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="15.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <CodeAnalysisRuleSet>$(MSBuildThisFileDirectory)..\CodeAnalysis.ruleset</CodeAnalysisRuleSet>
  </PropertyGroup>
  <ItemGroup>
    <AdditionalFiles Include="$(MSBuildThisFileDirectory)..\stylecop.json" />
  </ItemGroup>
</Project>

CodeAnalysis.nuspec

<?xml version="1.0" encoding="utf-8"?>
<package xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd">
    <metadata>
        <id>CodeAnalysis</id>
        <version>1.0.0</version>

        <owners></owners>

        <dependencies>
          <dependency id="Stylecop.Analyzers" version="1.0.2" />
        </dependencies>
    </metadata>
    <files>
      <file src="stylecop.json" />
      <file src="CodeAnalysis.ruleset" />
      <file src="CodeAnalysis.props" target="build" />
    </files>
</package>
