[Bug]: Specifying `RuntimeIdentifier` flattens package contents in output directory

[lostmsu]

NuGet Product Used

dotnet.exe

Product Version

.NET SDK 6.0.400

Worked before?

No response

Impact

I'm unable to use this version

Repro Steps & Context

1. Create a console .csproj
2. Add the following reference:

<PackageReference Include="LostTech.TensorBoard.Python.runtime.win-x64" Version="2.10.0-CI-2022-08-28-15" />

3. Add

<RuntimeIdentifier>win-x64</RuntimeIdentifier>
<Platforms>x64</Platforms>

4. Build

Expected: output directory should contain a subdirectory named native from the package with the contents of the package content tree structure preserved.

Actual: output directory get all the files from runtimes\win-x64\native directory of the package, without any directory structure (e.g. files are directly in the output directory, relative paths are not preserved).

Remarks

If RuntimeIdentifier is not supplied, the output directory gets runtimes\win-x64\native folder with the appropriate contents (e.g. relative file paths are preserved). However, I need the <RuntimeIdentifier> in order to be able to publish the project correctly.

Did also run into this issue. In my case I need <RuntimeIdentifier> to be able to unpack the correct native DLL's. But the used library (Chromium Embedded Framework) has a folder structure that needs to be preserved. Even worse it has a DLL present with the same name present twice:

• libEGL.dll
• swiftshader\libEGL.dll

Using <RuntimeIdentifier> results in swiftshader\libEGL.dll overwriting libEGL.dll which I think is even worse than just ignoring the files in the subfolder.

I would be happy to learn about a workaround while this issue is not resolved.

I haven’t found any workarounds for this problem, this is a really necessary thing

There is also a issue #7698 (comment)
There is no solution either
