Commented Unassigned: Could not install package [14097]

Could not install package 'NPOI 2.3.0'. You are trying to install this package into a project that targets '.NETPortable,Version=v4.5,Profile=Profile78', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
