Describe the Bug

When using a packaging project to pack both my MSBuild tasks/targets with the actual library references a netcore50 target is added to the lib outputs with a number of runtime references.

Additionally the net472 target framework from the MSBuild project is added while a 3rd MSBuild project is only added as a NuGet dependency for the net472 target.

Steps to Reproduce

See demo project...

• Have a multi-targeting library project
• Have a MSBuild targets project
• Have another MSBuild targets project that generates it's own core nuget.
• Have a msbuildproj packing project that packs each of these

Expected Behavior

The target frameworks should come from the multi-targeting library. The net472 target from the MSBuild project should be ignored... the netcore50 target should not exist. The "Core" project should be added as an all around reference.
