Not sure what your current build process is, but no longer need to "nuget.exe pack *.nuspec" because netcore will generate it for you with a simple dotnet pack. Everything compiles and the nupkg structure appears correct (though you may want to confirm I've correctly copied over the old nuspec properties such as authors, copyright, etc).
Apologies for the seemingly noisy sln/csproj changes; it's because I deleted the old csproj so the project guid was regenerated.
Very limited testing on this, helping out a LuckyNoS7evin stream.
