• [nitpick] The tests project was upgraded to Testcontainers 4.7.0, but the benchmark project still references 4.4.0. To avoid version drift and potential restore/runtime inconsistencies, align these to 4.7.0 (or centralize via Directory.Packages.props) in this project as well.

    <PackageReference Include="Testcontainers.PostgreSql" Version="4.4.0" />
    <PackageReference Include="Testcontainers.MsSql" Version="4.4.0" />
    <PackageReference Include="Testcontainers.MySql" Version="4.4.0" />
    <PackageReference Include="Testcontainers.Oracle" Version="4.4.0" />
