Reference nuget package project from another nuget package project in same solution

I am creating couple of .NET Standard 1.6 libraries that I want to publish as Nuget packages. They share a common libary that is a 3rd project in the same solution as the first two. The shared library has no value by itself, but I am assuming that if I want people to use both of these two libaries in the same project I should publish the shared library as a Nuget package as well. If I don't I am worried about multiple copies of the same shared library "colliding" or not properly warning when there are version mismatch issues.

Am I correct that the shared library needs to be a Nuget package as well? Is there a way to reference the shared library as Nuget package, but use is as if it was a project reference when developing / debugging the 2 main libraries in this solution? If I had to publish to Nuget.org and wait for the package be propagate through the Nuget.org system before using a changed version in a debug session that is REALLY going to slow down development. Note that these are .NET Standard projects. I found How to reference related projects in the same solution when Nuget packages are the required output but that doesn't seem to work with .NET Standard (getting errors during pack) and I am also not sure if .NET Standard not using nuspec files anymore also would cause a problem.

The .NET Standard still using .nuspec files, and using old school nuget pack and a .nuspec will resolve this issue.

As per document dotnet pack:

NuGet dependencies of the packed project are added to the .nuspec file, so they're properly resolved when the package is installed. Project-to-project references aren't packaged inside the project. Currently, you must have a package per project if you have project-to-project dependencies.

So, to include project-to-project references in NuGet packages, you need manually maintain a .nuspec file and add dependencies. You can refer to the Create .NET Standard packages with Visual Studio 2015 for detail info.

Besides, dasMulli has provided a simpler way to do this by involving adding and hooking up a custom target :

<Project>
  <PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
    <TargetsForTfmSpecificBuildOutput>$(TargetsForTfmSpecificBuildOutput);IncludeP2PAssets</TargetsForTfmSpecificBuildOutput>
  </PropertyGroup>

  <ItemGroup>
    <ProjectReference Include="..\testprivatelib\testprivatelib.csproj" PrivateAssets="All" />
  </ItemGroup>

  <Target Name="IncludeP2PAssets">
    <ItemGroup>
      <BuildOutputInPackage Include="$(OutputPath)\testprivatelib.dll" />
    </ItemGroup>
  </Target>
</Project>

The source code comes from: "donet pack" is not including project references
