Sorry, I was looking from a expanded view of your post from the main landing page: ArcGIS Runtime SDK for .NET I didn't realize attachments are only visible from within the message. Anyway, I used your helper class with this very simple sample. I commented out the workaround of replacing g with PolygonBuilder but I'm not able to reproduce the issue.  It seems to work without AccessViolationException. I ran the sample against the final released version 10.2.4.748              xmlns:esri="http://schemas.esri.com/arcgis/runtime/2013">     <Grid x:Name="LayoutRoot"           Background="White">         <esri:MapView x:Name="MyMapView">         <esri:Map >             <esri:ArcGISTiledMapServiceLayer ServiceUri="http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer" />                 <esri:GraphicsLayer ID="MyLayer" />             </esri:Map>         </esri:MapView>         <StackPanel Orientation="Horizontal"                     VerticalAlignment="Top"                     HorizontalAlignment="Center">             <Button Content="Flash"                     Click="Button_Click" />         </StackPanel>     </Grid         private async void Button_Click(object sender, RoutedEventArgs e)         {             string message = null;             try             {                 var geometry = await MyMapView.Editor.RequestShapeAsync(DrawShape.Envelope);                 var graphic = new Graphic() { Geometry = geometry, Symbol = new SimpleFillSymbol() };                 var layer = MyMapView.Map.Layers["MyLayer"] as GraphicsLayer;                 layer.Graphics.Add(graphic);                 clsGraphicHelper.FlashGeometry(MyMapView, geometry, geometry.Extent.GetCenter());             }             catch (TaskCanceledException)             {             }             catch (Exception ex)             {                 message = ex.Message;             }             if (!string.IsNullOrWhiteSpace(message))                 MessageBox.Show(message);         } ...

Hi, Thank you for reporting this bug.If you had tried to move the geometry using EditGeometry, Editor, or EditorWidget, there is currently a bug that SpatialReference becomes null if geometry was Polyline/Polygon after this operation. We will try to include the fix in future versions. In the meantime, you can subscribe to EditGeometry.GeometryEdit and correct the geometry         SpatialReference spatialReference;         private void EditGeometry_GeometryEdit(object sender, EditGeometry.GeometryEditEventArgs e)         {             if (e.Action == EditGeometry.Action.GeometryMoved)             {                 // this should not happen                 if (e.Geometry.SpatialReference == null)                 {                     if (spatialReference == null && e.Graphic.Geometry.SpatialReference != null)                         spatialReference = e.Graphic.Geometry.SpatialReference;                 }             }             if (e.Action == EditGeometry.Action.EditCompleted)             {                // this is just a workaround                 if(e.Graphic.Geometry.SpatialReference == null && spatialReference != null)                     e.Graphic.Geometry.SpatialReference = spatialReference;             }         } ...

Hi Phil, Do you mind sharing your code? I could not reproduce the issue. DecimalDegrees is a supported unit: ArcGIS Runtime SDK for Microsoft WPF - Library Reference .

Hi John, Thank you for your post. Based on the property you are using, ServiceUri, you might be referring to another product. In the future, please post to: ArcGIS Runtime SDK for .NET I believe ServiceUri is not a property you can set once the layer is initialized. I tweaked your sample so it can run against latest release 10.2.4. Also, if you need your base layer to point to a new service endpoint, you need to remove the layer from map before adding a new instance with new ServiceUri. No refresh necessary, the same InitialViewpoint, you've set will be used for the new layer. Note, however that replacing tiled layers like this assume you have matching SpatialReference. In your case, the services were all WKID=3857, which is okay. Otherwise, you will need to clear MapView.SpatialReference also.        xmlns:esri="http://schemas.esri.com/arcgis/runtime/2013">     <Grid>         <esri:MapView x:Name="MyMapView">             <esri:Map InitialViewpoint="-9556486,4312801,-9551302,4315166">                 <esri:ArcGISTiledMapServiceLayer                                              ID="BaseMap"                                              ServiceUri="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer">             </esri:ArcGISTiledMapServiceLayer>                   </esri:Map>         </esri:MapView>         <StackPanel Orientation="Horizontal"                     VerticalAlignment="Top"                     HorizontalAlignment="Center">             <Button Content="Image"                     Click="Button_Click" />             <Button Content="Road"                     Click="Button_Click" />             <Button Content="Topo"                     Click="Button_Click" />         </StackPanel>     </Grid> private void Button_Click(object sender, RoutedEventArgs e)         {             var content = ((Button)sender).Content.ToString();             var layer = MyMapView.Map.Layers["BaseMap"] as ArcGISTiledMapServiceLayer;             if (layer != null)             {                 MyMapView.Map.Layers.Remove(layer);                 layer = new ArcGISTiledMapServiceLayer() { ID = layer.ID };             }             switch (content)             {                 case "Image":                     {                         layer.ServiceUri = "http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer";                         break;                     }                 case "Road":                     {                         layer.ServiceUri = "http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer";                         break;                     }                 case "Topo":                     {                         layer.ServiceUri = "http://server.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer";                         break;                     }             }             if (layer != null)                 MyMapView.Map.Layers.Insert(0, layer);         } ...

Hi Joao, Sorry for the delay in my response. I had just tried this on the latest 3.2 release (10.2.1.431) and was not able to reproduce. Editing geometry completes by clicking inside the polygon even if MoveEnabled, RotateEnabled and ScaleEnabled had been set to false. Jennifer ... View more

Are you working with ServiceFeatureTable? Would it be possible for you to share also the JSON response from the QueryRelatedAsync call? I believe this exception has something to do with parsing the Fields in the JSON and would happen only if Fields with type esriFieldTypeString is missing length property. Thanks. Jennifer ...

In addition to Mike's response, you may also use QueryAsync providing geometry in the SpatialFilter if working with ArcGISFeatureTable/ServiceFeatureTable or GeometryEngine.Intersects method. ... View more

Hi, Thank you for submitting this bug report. As part of optimizing the serialization of layers for printing, GraphicsLayer without Graphics are ignored. But we should include a check that the GraphicsLayer is not a FeatureLayer for this may also mean that the layer is simply not initialized (as in your case). For the meantime, as a workaround you can add a temporary graphic to a FeatureLayer that is not yet initialized before you execute print. if(!layer.IsInitialized) // Note that if FeatureLayer is already initialized, this may cause an edit.    layer.Graphics.Add(new Graphic()); // this graphic will be cleared after FeatureLayer.UpdateCompleted is raised. mapLayers.Add(layer); Do the workaround above before executing a print. In code below, t is PrintTask, r is the PrintResult.                 var r = await t.ExecuteTaskAsync(new PrintParameters(mapLayers, mapExtent)                 {                     ExportOptions = new ExportOptions()                     {                         OutputSize = new Size(200, 200)                     }                 }); We'll try to get this fixed in future releases of the API.

Yes, Layer is not a control. You can probably bind to Map, ConverterParameter with ID of your layer and a Converter that would get the layer given ID instead. ... View more
