I am upgrading from ArcGIS 10.2.3 to the latest 100.2.1. The amount of time that has passed is huge so I am having to translate old ways to new ways. I used to be able to specify the OutFields when adding a FeatureLayer to an ESRI Mapview so that only the fields I cared about would be transferred over the wire to improve performance. How do I do that now? I don't see a way to specify OutFields.
