Runtimes

How to include the all MediaInfo.dll runtime native libraries in .csproj:

<ItemGroup>
    <Content Include="$(NuGetPackageRoot)\MediaInfoDLL\25.7.0\lib\netstandard2.0\x64\MediaInfo.dll">
        <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
        <DestinationFolder>$(OutDir)MediaInfo-x64\</DestinationFolder>
        <Link>runtime-x64\MediaInfo.dll</Link>
    </Content>
    <Content Include="$(NuGetPackageRoot)\MediaInfoDLL\25.7.0\lib\netstandard2.0\x86\MediaInfo.dll">
        <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
        <DestinationFolder>$(OutDir)MediaInfo-x86\</DestinationFolder>
        <Link>runtime-x86\MediaInfo.dll</Link>
    </Content>
    <Content Include="$(NuGetPackageRoot)\MediaInfoDLL\25.7.0\lib\netstandard2.0\arm64\MediaInfo.dll">
        <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
        <DestinationFolder>$(OutDir)MediaInfo-ARM64\</DestinationFolder>
        <Link>runtime-arm64\MediaInfo.dll</Link>
    </Content>
</ItemGroup>

and remove the auto copying library:

<Target Name="ReduceReleasePackaging" AfterTargets="Build">
    <!-- MediaInfoDLL will copy the MediaInfo.dll file according to the architecture, we do not use this usage so delete it manually -->
    <Delete Files="$(OutputPath)\MediaInfo.dll" Condition="Exists('$(OutputPath)\MediaInfo.dll')" />
</Target>
