Failed to load assembly Microsoft.SqlServer.Management.IntegrationServicesEnum.

I'm having an issue with an application deployed from Azure DevOps to a Windows Server 2019 machine.
Turns out the Build Pipeline isn't copying all the Assemblies from sqlserver.smo.2016.13.0.0.2.nupkg after the NuGet Restore option.

The log shows :

Adding package 'SQLServer.SMO.2016.13.0.0.2' to folder 'D:\a\1\s\packages'
Added package 'SQLServer.SMO.2016.13.0.0.2' to folder 'D:\a\1\s\packages'
Added package 'SQLServer.SMO.2016.13.0.0.2' to folder 'D:\a\1\s\packages' from source 'https://api.nuget.org/v3/index.json'

However just one Assembly is missing and that is : Microsoft.SqlServer.Management.IntegrationServicesEnum.dll

The Packages.Config references the NuGet Package :
[package id="SQLServer.SMO.2016" version="13.0.0.2" targetFramework="net472" /]
