Experimental nuget needs autolink-windows when app consumes library #csharp

Problem Description

Hello everybody,

I work on an RNW v0.70.19 project where I have a csharp app that consumes a lot of csharp and cpp libraries, all in RNW as well. Recently I'm trying to use the experimental nuget to improve the build performance of my solution, but I've been having some problems making use of the experimental nuget in my project.

I had a lot of errors in my project, so I decided to test it in a new app to find out if my project's architecture is compatible with the RNW standard.

How I did an PoC of experimental nuget:

1. I created a new app in csharp, because the app in my project is csharp.
2. Also created two libraries, one in scharp and the other in cpp. Added both as dependencies in my app, installed and did autolink.
3. I noticed the csharp library references Microsoft.ReactNative.Managed and Microsoft.ReactNative.Managed.CodeGen locally (from node_modules) projects, and even includes them within the solution.
4. Then I removed manually this two projects of my solution and try to build again, but as these projects were added by autolink, I got autolink error.
   

NOTE: If I added just cpp library, the solution build corretly. So I believe that the error is only in the csharp library.

Steps To Reproduce

1. Clone https://github.com/caiovictor/rnw-070-experimental-nuget
2. Open app solution ./myApp/windows/myApp.sln on VS and build.
3. Get autolink error.

Expected Results

The solution (app + library) is expected to build correctly.

No response

Clone the linked PoC repository, open ./myApp/windows/myApp.sln in Visual Studio, and reproduce the autolink error while building. Compare the C# library setup with the working C++-only case and trace how the experimental NuGet projects are added by autolink; done means the app and library solution builds successfully.
