Central Package Management - Where is the correct place to add IncludeAssets and PrivateAssets options?

[dfaivre]

i.e. for including coverlet.collector:

<PackageReference Include="coverlet.collector">
    <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    <PrivateAssets>all</PrivateAssets>
</PackageReference>

Do the IncludeAssets and PrivateAssets tags go in the .csproj file or in the Directory.Packages.props file?
