It looks like you need to add an elevation source to the scene view base surface. See this sample for an example of how to do that in code: https://developers.arcgis.com/net/wpf/sample-code/get-elevation-at-a-point/

The important lines are:

Uri elevationUri = new Uri("https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer"); Surface baseSurface = new Surface(); baseSurface.ElevationSources.Add(new ArcGISTiledElevationSource(elevationUri)); myScene.BaseSurface = baseSurface;

Alternatively try experimenting with the SurfacePlacement property of you "slpkLayer". For more info see https://developers.arcgis.com/net/api-reference/api/netwin/Esri.ArcGISRuntime/Esri.ArcGISRuntime.Mapping.SurfacePlacement.html.

Thanks you MichaelBranscomb

But vegetations and highways is not showing after setting the elevation source.

see the following figure
