CodePudding user response:

It looks like this package was authored to use the content folder with a .cs.pp file transform that were previously rendered and copied to the project folder for projects using packages.config to reference NuGet packages.

This is no longer supported for SDK-style projects which use PackageReference. The package author would need to switch to (or add) contentFiles to support PackageReference or create a pre-built binary (.dll file).
