Microsoft.Data.SqlClient - Could not load file or assembly 'System.Security.Permissions, ...'

Microsoft.Data.SqlClient를 사용하던,

<PackageReference Include="Microsoft.Data.SqlClient" Version="5.1.2" />

프로젝트를 근래에 새로 빌드해 실행했더니 이런 오류가 발생합니다.

System.IO.FileNotFoundException
  HResult=0x80070002
  Message=Could not load file or assembly 'System.Security.Permissions, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.
  Source=Microsoft.Data.SqlClient

어쩔 수 없습니다. 오류 메시지에 따라, System.Security.Permissions 패키지를 새로 추가해야 합니다.

Install-Package System.Security.Permissions -Version 6.0.0
