A bait-and-switch project fails to build

I am trying to create a bait-and-switch project with both the library and the app in the same solution.

This is a common way to create plugins or other shared APIs.

In my solution I have 4 projects:

  1. The CORE LOGIC project   (netstandard2.0 - MyApp.dll)
  2. The TIZEN APP project for Tizen OS   (tizen40 - MyApp.Tizen.dll)
  3. The REFERENCE LIBRARY with a reference API   (netstandard2.0 - Library.dll)
  4. The TIZEN LIBRARY for Tizen OS   (tizen40 - Library.dll)

The project references are set up as such:

  • The TIZEN APP references
    • The CORE LOGIC references

As you can see, the Tizen app project wants the Tizen implementation library, but the core logic project wants the reference library. In other project types, the Tizen library has the same name as the reference library, but the Tizen library is preffered because the it was specifically referenced and the reference library is only added via transititive references.

I have created a sample that shows the error here:

If you build this, this is the error message:

1>------ Build started: Project: TheClassLibrary, Configuration: Debug Any CPU ------
2>------ Build started: Project: TheClassLibrary.Tizen, Configuration: Debug Any CPU ------

sadly, links aren't allowed, so just copy-paste the bold urls - at least for me
