Native libraries not included in nuget with EmbeddedNativeLibrary

Question

Hello,

We have a series of native C++ libraries (.so) which are being packaged into a native library nuget.
They are added with a build type of EmbeddedNativeLibrary.

Everything compiles correctly and the nuget is created.

However, the native libraries are not included in the nuget.
I have tried checking the option "include in package" as well as selecting the option "Copy to output directory"->Always, with no effect.

Is this a known bug ?
Is there a workaround ?

Here are my installation details :

Answer 1

Hold everything !
False problem.
The libraries are indeed there, compressed into the dll.
