I see that WMTS layers are already supported in ArcGIS Runtime 100.1. I came across some API documentation showing a WMSLayer class, which is from version 100.2. Am I correct that 100.2 has not been released yet?
Are there any plans, hopes, dreams, or wishes to support WFS in future releases?
WMS Layer is coming in the next update
100.2 isn't released yet. Where did you find 100.2 documentation?
WFS is on the roadmap but there's nothing to announce at this point.
100.2 is now out with WMS support.
