Where are the NI Visa references for use in .Net applications

[Binoptics]

 I want to use NI Visa in my C# .net application but can't find the references mentioned as required in this article (https://www.ni.com/en/support/documentation/supplemental/17/archived--c--and-visual-basic--net-instr...), namely NationalInstruments.Common and NationalInstruments.VisaNS

From https://www.ni.com/en/support/downloads/drivers/download.ni-visa.html#306022 I downloaded  NIVISA1400full_downloader.exe, installed it, rebooted the workstation.  I did find the reference to NationalInstruments.Common but not  NationalInstruments.VisaNS .

Is there an updated example of NI-Visa with .Net, did I install the incorrect NI-Visa components?
