Hi,
Is this possible to add Multipatch feature class to map using ArcGIS Runtime .NET SDK?
ArcGIS Runtime works with Scene Layers - you can use ArcGIS Pro to publish/share your Multipatch feature class as a Scene Layer Package for offline/disconnected use or as a Scene Layer service for online/connected use:
