Extrude geometries with ArcGis runtime version 100.1

[ManelKEDDAR]

Hello ,

ineed to create a 3D extruded Geometries with arcGIS runtime v 100.1 , i need to know how to do that or is it possible to do that for exemple to extrude a 3D polygon vertex with varying the z value, i don't want to use symbols of sceneView . in arcObjects .net 10.1 SDK there's IConstructMultiPatch.ConstructExtrude Method i just do wonder if there's something similar on arcGis runtime v100.1

thanks in advance

cheers
