    Hi @CC ,

    Quote from the old thread missing Microsoft.SqlServer.ManagedDTS.

    In the Add Reference dialog window, click on the browse tab. Then navigate your way to:

    C:\Program Files\Microsoft SQL Server\90\SDK\Assemblies

    There you will find the Microsoft.SQLServer.ManagedDTS.dll, select it and hit okay.

    For Microsoft.SqlServer.Management.IntegrationServices, we can get this once we installed SSIS. Please check you have installed SSIS from SQL server configuration manager. Below is the test that I check today, once I add the SSIS feature in SQL 2019 instance in my environment, I get this file.


    By the way, what is the version of your SQL server.
