How to share common assembly attributes without failing to publish?

Question

I have created a class Library, which has some static classes with const strings, which are serving some common strings* for the assembly attributes:

//Assembly: Conwell.Manifest
namespace Conwell.Manifest.AssemblyInfos
{
    public static class AdministrationAssemblyInfo
    {
        public const string Company = "Foo";
        public const string Trademark = "Bar";
        public const string Copyright = "Baz";
        public const string AssemblyVersion = "1.0.*";
        public const string ProductName = "Administration";
    }
}

In my MVC Project I have this AssemblyInfo:

//Assembly: Conwell.Administration Properties:AssemblyInfo.cs
using System.Reflection;
using System.Runtime.InteropServices;
using Conwell.Manifest.AssemblyInfos;

// CLR Attributes
[assembly: ComVisible(false)]
[assembly: Guid("16abe67b-6992-4a20-83bb-decad83600f0")]
[assembly: AssemblyVersion(AdministrationAssemblyInfo.AssemblyVersion)]
[assembly: AssemblyCulture("")]
[assembly: AssemblyConfiguration("")]

// Informational Attributes
[assembly: AssemblyCompany(AdministrationAssemblyInfo.Company)]
[assembly: AssemblyCopyright(AdministrationAssemblyInfo.Copyright)]
[assembly: AssemblyTitle(AdministrationAssemblyInfo.ProductName)]
[assembly: AssemblyDescription(AdministrationAssemblyInfo.ProductName)]
[assembly: AssemblyProduct(AdministrationAssemblyInfo.ProductName)]
[assembly: AssemblyTrademark(AdministrationAssemblyInfo.Trademark)]

This compiles fine in Debug and Release Mode.

I just tried to publish the whole project, and encountered an error I do not realy unterstand:

The type or namespace name 'Conwell' could not be found (are you missing a using directive or an assembly reference?)

The tmp file contains this:

18.03.2018 23:59:18

The output is this:

The warnings are basicly some custom ones, using ObsoleteAttribute.

Has this something todo with enabled precompilation?

What I have tried so far:

• Creating a static method in my AdministrationAssemblyInfo, calling Console.WriteLine. This method I have called from global.asax in order to preclude any optimization, since all the library contains are const.
• Clean Solution
• Restart PC

I have absolute no clue, what is causing the issue.

_{* my main motivation is to have a single location for changing the version, since I use a lot of class libraries}
