Directory.Packages.props:16

• CodeAnalysisVersion was bumped to 5.0.0, but Microsoft.CodeAnalysis.Analyzers remains pinned to 4.14.0 in the same file. This mixed Roslyn major version set can lead to restore/build issues or analyzer/SDK incompatibilities. Consider updating the analyzer package to a matching version (or documenting/justifying why it must remain at 4.14.0).

    <CodeAnalysisVersion>5.0.0</CodeAnalysisVersion>
    <CodefixTestingVersion>1.1.2</CodefixTestingVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageVersion Include="DiffPlex" Version="1.9.0" />
    <PackageVersion Include="Microsoft.CodeAnalysis.Analyzers" Version="4.14.0" />
    <PackageVersion Include="Microsoft.CodeAnalysis.Common" version="$(CodeAnalysisVersion)" />
