Packaging TargetFramework Specific Native Libraries

[Danielku15]

My question relates to this NuGet Feature: https://learn.microsoft.com/en-us/nuget/create-packages/native-files-in-net-packages

I am in the need to ship some additional native libraries together with my NuGet and normally I would place them within runtimes\win-x64\native to have them available at runtime.

For our anti-tampering / licensing system I have a tooling which will create native libraries specific to the .net DLLs as a post-build step. Hence I have dlls like this after compilation:

• bin\Release\net48\win-x64\MyManaged.dll (.net assembly)
• bin\Release\net48\win-x64\MyManagedAntiTamper.dll (native library - matching the net48 MyManaged.dll)
• bin\Release\net9.0\win-x64\MyManaged.dll (.net assembly)
• bin\Release\net9.0\win-x64\MyManagedAntiTamper.dll (native library - matching the net9.0 MyManaged.dll)

How can I now setup my nupkg that on compilation against a .net target framework the correct MyManagedAntiTamper.dll will be copied to the output directory? I'd need a feature like runtimes\win-x64\lib\net48\ but for native libs: runtimes\win-x64\native\net48

Unless I can avoid it, I want to avoid naming the MyManagedAntiTamper.dll like MyManagedAntiTamper_net48.dll + MyManagedAntiTamper_net9.0.dll and let them being copied to all target framework outputs.
