MSBuild multiple dll in a single NuGet package

Question

I have a Visual Studio 2017 solution that contains two projects:

Foo.csproj
Foo.Core.csproj

Both of these projects target multiple framewor

Answer 1

I have recently discovered that you CANNOT set defaults for the Nuspec Properties you want to replace in the msbuild command line e.g. if a metadata value is set in the .csproj file of "2.0.0" and you run:

msbuild myproject.csproj -t:pack -p:Configuration=Release -p:NuspecProperties=Configuration=Release;PackageVersion=1.2.3

Your .nupgk file will have the version 2.0.0 still. Annoyingly the MS documentation is not clear on this and no error is displayed.
