Architecture-specific folders

What is the correct way to create a c# project with native dependencies

and make them flow to other project that depend on it ?
We are able to do it in nuget placing assets in the runtimes/rid/folders, but what is the csporj equivalent ?

Thanks

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

I'd ran into this. PackageReference supports the rid specification, but ProjectReference doesn't. I had to workaround by creating a temporary nupkg.

I'm from dotnet/runtime#65420,
I think we need some Item like <NativeBinaryReference Include="native.dll" Rid="win-x64" /> to implement this, this can be use to both genereate nuget package and also for project reference.

Or , we should make the metadata PackagePath to be supported both on <PackageReference /> and <ProjectReference />.

From dotnet/runtime#65420 too.

Now that both iOS and Android supports this NuGet convention. However, if I don't want to create a native package, I need to use AndroidNativeLibrary for Android, but NativeReference for iOS. When it comes to WebAssembly, NativeFileReferences is required. Furthermore, it looks like such an equivalent does not exist for Windows/Linux/macOS.

Platform	Item to Use
iOS	NativeReference
Android	AndroidNativeLibrary
WebAssembly	NativeFileReferences
Others	???

I really hope we have a unified item to cover all these differences.
