How/where do you download Microsoft.SqlServer.ConnectionInfo, Version=16.200.0.0?

Please clarify how you are getting the error.

SmoExtended
It's part of SMO = Server Management Objects, see
https://learn.microsoft.com/en-us/sql/relational-databases/server-management-objects-smo/installing-smo?view=sql-server-ver15
I installed SMO and ConnectionInfo from Nuget. It looks like the versions aren't in synch.

Hi @Shiela E 2021 , I tried to install Microsoft.SqlServer.SqlManagementObjects NuGet package (version 161.47008.0) and after I built the project, I can see that the version of Microsoft.SqlServer.SmoExtended is 16.200.47008.0 and the version of Microsoft.SqlServer.ConnectionInfo is 16.200.47008.0. The version of them are both higher than 16.200.0.0. Please try to reinstall/restore this NuGet package and test again. Besides, does your project include/reference a lower version(10.0.0.0) of Microsoft.SqlServer.ConnectionInfo dll file?
