I'm looking for something similar to IActiveView.Refresh from the ArcObjects world. My use case is that I'm running a tool that updates the features in the layer, and I need a way to get the map to re-draw from my code similar to how the out-of-the-box tools are doing automatically.
In my particular example, I am using UNME and am validating the Utility Network topology, which causes the Dirty Areas polygon layer to remove polygons for areas that are valid. I tried looking around for a way to invalidate just that layer but wasn't having much luck. Any clues for how to get the layer to refresh properly? This layer is coming from a feature service published through ArcGIS Enterprise per requirements of the UNME.
