Here is the .csproj content:

<Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFrameworks>net6.0;net7.0</TargetFrameworks>
        <ImplicitUsings>enable</ImplicitUsings>
        <Nullable>enable</Nullable>
    </PropertyGroup>

    <ItemGroup>
      <PackageReference Include="BenchmarkDotNet" Version="0.13.2" />
      <PackageReference Include="Microsoft.Extensions.Logging" Version="7.0.0" />
      <PackageReference Include="Microsoft.Extensions.Logging.Console" Version="7.0.0" />
    </ItemGroup>

</Project>

The constructor needs to set a Logger<Program>, apologies, remnants :)
