Description

Problem description

According to the information in November 2021 CU for SharePoint 2016 and 2019 it is no longer recommended to have Microsoft SQL Server 2012 Native Client (sqlncli.msi) installed on the SharePoint servers as it's no longer used. Is it possible to remove this from the prerequisite installation?
I've not tested if the prerequisite installer still enforces installation of sqlncli.msi

Research direction

Start with the SPInstallPrereqs resource entry point and inspect how the SQLNCli property and SharePoint build or CU version are evaluated. Confirm the November 2021 CU references in the issue, then identify the resource tests, if present; done means sqlncli.msi is not installed for SharePoint 2016 and 2019 November 2021 CU or newer.
