CS8700 : Multiple analyzer config files cannot be in the same directory, unable to build with seperate .editorconfig files

[olejsc]

Version Used: C#12
Visual studio 2022 17.12.3
Steps to Reproduce:

1. Create a new console application solution + console application csproj
2. Add a new class library to solution, lets call it classLib
3. Right click on console application, generate new editorconfig (intellicode)
4. Copy the generated .editorconfig from console application proj to the root directory of the classLib
5. Verify both csproj files have their "own" .editorconfig, by right clicking project in visual studio 2022, and click edit project.
   Ensure both projects HAS this in their .csproj:

  <ItemGroup>
    <EditorConfigFiles Include=".editorconfig" />
  </ItemGroup>

6. Add a project reference to classLibfrom console application. Create a simple class in classLib and use it to just console.writeline a property in console application.

7. Compile and run the project.

Observe Error:

A minimal repro, with source-code provided, is ideal. Most compiler/language issues can be distilled into a snippet that can be pasted into sharplab.

Note: I've also tried this solution from stackoverflow, to no avail:

I've also tried ton Visual studio 2022 17.12.4 , to no avail.

I originally encountered this when I had a customer project with this folder structure:

• Root folder
• XXX.sln (solution file)
• WebAPiA
  • .editorconfig
  • WebAPIA.csproj
  • ... misc files for webapi A
  • NOTE: Has a reference to classLibB
• ClassLibB
  • .editorconfig
  • misc classes
  • no project dependencies

The issue also persist if i add the stylecop nuget to classLibB

Edit, things I've tried:

• wipe bin/obj folder
• unload/reload project
• the solution mentioned here for both projects: https://stackoverflow.com/questions/62274932/cs8700-multiple-analyzer-config-files-cannot-be-in-the-same-directory-but-onl
• downgraded visual studio 2022
• clean'ed solution & both projects multiple times + rebuild.

Appreciate any thoughts on this.
