I was under the impression that the Data Interop extension was needed to use a WFS service in ArcGIS Desktop, as outlined here. The page specifically mentions that a DI license is required.
Now I found another page that shows something different:
There is no mention of DI, and apparently there is a new option under GIS Servers ('Add WFS Server').
I don't have this option, in ArcGIS 10.3.1 or 10.4.1, so how do I get it? I thought I needed to install DI after all, so I did that, but the option is still not there, nor can I find a way to add it manually. Is this part of the Production Mapping extension?
I have an ArcGIS Enterprise license.
