Copy a dll to AppX folder and Publish Folder

[ahipki]

Hello,

I need a dll : vcinet.x64.dll.
When I work in local environment, I always need to copy this dll to the folder AppX because the folder doesn't want to be copied in AppX folder. The dll is in the parent folder. If I had understand AppX utility, it's only for when I run the app.
So I decided to put this dll in my project files and a script to copy it.
I put the dll on Resources\vcinet\x64\vcinet.x64.dll

I put this on my csproj :

<ItemGroup>
  <Content Include="Resources\vcinet\x64\vcinet.x64.dll">
    <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    <CopyToPublishDirectory>Always</CopyToPublishDirectory>
  </Content>
</ItemGroup>

And this :

 <ItemGroup>
   <None Update="Resources\vcinet\x64\vcinet.x64.dll">
     <CopyToOutputDirectory>Always</CopyToOutputDirectory>
   </None>
 </ItemGroup>

And I want to add a "script" :
I tried :

  <Target Name="CopyVcinetDllToOutputDirectory" AfterTargets="Build">
    <Copy SourceFiles="Resources\vcinet\x64\vcinet.x64.dll" DestinationFolder="$(OutputPath)annie" />
  </Target>

It works, I have my annie folder created with the dll when I build.
When I publish :

  <Target Name="CopyVcinetDllToPublishDirectory" AfterTargets="Publish">
    <Copy SourceFiles="Resources\vcinet\x64\vcinet.x64.dll" DestinationFolder="$(PublishDir)vcinet\x64" />
  </Target

If I use 7-zip to unpackage the .msix, I don't see any vicinet folder
I tried $(TargetDir) instead of $(PublishDir) and also $(OutDir) and also $(OutputPath) and it doesn't work.
I also tried :

  <Target Name="CopyVcinetDllToPublishDirectory" AfterTargets="Publish">
    <Exec Command="xcopy /Y /I /E &quot;$(TargetDir)Resources\vcinet\x64\vcinet.x64.dll&quot; &quot;$(PublishDir)vcinet\x64\vcinet.x64.dll&quot;" />
  </Target>

I tried with AfterPublish instead of Publish and it doesn't work
I also tried this but not working either.

  <Target Name="CopyVcinetDllToPublishDirectory" BeforeTargets="_ConvertItems;_CalculateInputsForGenerateCurrentProjectAppxManifest">
    <Copy sourcefiles="Resources\vcinet\x64\vcinet.x64.dll" DestinationFolder="$(PublishDir)vcinet\x64" />
  </Target>

---

I also want, for the debug, the dll in my AppX folder so I tried

  <Target Name="CopyVcinetDllToOutputDirectory" AfterTargets="Build">
    <Copy SourceFiles="Resources\vcinet\x64\vcinet.x64.dll" DestinationFolder="$(OutputPath)AppX\vcinet\x64" />
  </Target>

I see my vcinet folder in AppX folder.
But when I launch the app, the AppX folder disappear and reappear without de folder vcinet

Thanks if you find me the miracle command :)

(To have the file in my AppX, I moved from Resources to vcinet directly at the root of the project)
