To select features in a layer, you could use: SelectFeaturesAsync() method (Method SelectFeaturesAsync (arcgis.com)). To get selected features from a layer, you could use GetSelectedFeaturesAsync() (Method GetSelectedFeaturesAsync (arcgis.com)). The SelectFeaturesAsync() takes a QueryParameters; passing a WhereClause with "1=1" will select all the features in a layer. After calling the GetSelectedFeaturesAsync(), you could iterate through all the selected features and buffer (Method Buffer (arcgis.com)) their geometries one by one. The buffer geometry could be added to a FeatureLayer FeatureTable(Class FeatureTable (arcgis.com)) (by creating new features using the geometry from each buffer) , or you could create graphics from them and add that to a GraphicsOverlay (Class GraphicsOverlay (arcgis.com)). If you choose to add the buffer feature to the layer/table, it will be like any other feature, and if you want to remove it you will have to query it to find it and delete it (would usually help if there is a unique attribute value you can query for to identify which features are buffers and which are not). If you choose to add to a GraphicsOverlay, then at runtime you can call GraphicsOverlay.Graphics.Clear() to clear all the graphics.

Calling "poly = GeometryEngine.Simplify(poly);" on your polygon before adding it to the GraphicsOverlay should resolve the issue. private void addPolygon(string polygonJson) { var poly = Geometry.FromJson(polygonJson); poly = GeometryEngine.Simplify(poly); var graphic = new Graphic { Geometry = GeometryEngine.Project((Polygon)poly, new SpatialReference(3006)) }; testLayer.Graphics.Add(graphic); }

Could you please provide the MMPK you are testing with?

Try changing the GraphicsOverlay SceneProperties SurfacePlacement property. Here is a sample on how to do that: Surface placement | ArcGIS Runtime API for .NET | ArcGIS for Developers

Thanks for the info @zjoerg. I was able to reproduce with ArcGIS Runtime .Net 100.11 as well. It does seem to be the same issue identified in the the ArcGIS Runtime Android SDK: BUG-000117942.

Does Runtime have any issues with the deleted feature, or does it seem to work as expected?

SubtypeSublayers only controls display. In order to query a SubtypeSublayers you will have to query the SubtypeFeaturelayer's table. To narrow down data for the SubtypeSublayer, you can set the where clause in the QueryParameters to include a check for the subtype code . ((ArcGISFeatureTable)subtypeFeatureLayer.FeatureTable).LayerInfo.SubtypeField + " = " + subtypeSublayer.Subtype.Code

Justin, Have you tried using KmlNode.SaveAsAsync()? KmlNode.SaveAsAsync Method

Steven, Identify will not return features that are not part of the definition expression on a layer. One workaround you can try is to have another layer (same data source, no definition expression) but set the layer opacity to 0; since opacity will be ignored with identify... Identify features—ArcGIS Runtime SDK for .NET | ArcGIS for Developers, if you identify features on this new layer you will get the features you want. In this case you will only see the features returned by the definition expression, but you can identify all the features. Tony

Also make sure that the SpatialReference of your envelope matches that of your layer.
