I need to use native C libraries in my library (that supports several Core TFs and .NET Framework) which is published via NuGet. I configured it via a .csproj file and a runtimes folder, but I noticed that when I consume my NuGet via dotnet add package ... in some cases, the native libraries are not copied into the expected folder after consuming, however when I use the Visual Studio NuGet Package Manager and select "Manage NuGet Packages for Solution", all files are placed into correct places.
So, I assume that NuGet package manager makes more steps than just calling dotnet add package ..., but it's unclear what exactly happens.
