I am looking for a way to create an \"Imports Newtonsoft.Json.Linq\" in my SSIS script task, but this is apparently not as simple as a \"manage NuGet Packages\" in SSIS. So
You have to add Newtonsoft.Json
dll file to the following directories
(1) .Net Framework dll directory
C:\Windows\Microsoft.NET\Framework\v[.net installed version]\
example
C:\Windows\Microsoft.NET\Framework\v4.0.30319\
(2) SQL server data tools dll runtime directory
C:\Program Files (x86)\Microsoft SQL Server\[SQL Server version]\DTS\Binn
example
C:\Program Files (x86)\Microsoft SQL Server\130\DTS\Binn
After that, in the Script Task, go to project explorer, you and then add this dll as a reference, it will appear in the references listed.
