Thanks for the report.

One of the motivations for moving to satellite assemblies was to move most of the large resource files outside of the assembly so we don't have to deploy multiple copies of them (1 copy per target framework). The satellite assemblies are actually target framework neutral. However, after experimenting with the default fallback rules for PackageReference, it seemed at the time that there was no option that would allow us to deploy only 1 copy of the resources while multi-targeting our main assemblies. The closest we could get was to target netstandard1.0. Unfortunately, the reference assemblies it automatically brings in were an undesired side effect and are completely unnecessary.

After taking another look, it looks like there is a AssetTargetFallback property to override the default behavior. So, we will have to see whether changing the default behavior will work without bringing in undesired dependencies.
