PackageReference doesn't reference library

Question

When I try to add a package reference to the .csproj file I am having the problem that the actual DLL is not referenced in the project. My example is:

<ItemGroup>
    <PackageReference Include="Newtonsoft.Json">
        <Version>11.0.2</Version>
    </PackageReference>
</ItemGroup>

The package appears in the Nuget package manager but not in the project's "References" list and the assembly cannot be accessed from the project.

I am using Visual Studio 15.7.4

Thanks
