To test your snippet i used the following code to define the envelope:   var env = MapView.Active.Extent; (xMax, yMax) = (env.XMax, env.YMax); (xMin, yMin) = (env.XMin, env.YMin);   This works for me, but the graphic i get is a bow tie.   Wolf_0-1666616725822.png Because you don't get a graphic at all, i assume that your projection for your a, b, c and d values needs to be defined.  I don't know what your projection is, but you have to add it here:   Polygon poly = PolygonBuilderEx.CreatePolygon(plyCoords, map.SpatialReference);   Replace map.SpatialReference with the spatial reference for your corner coordinates.  I.e. SpatialReferences.WGS84 if you are using lat/long. ...

I attached two sample solutions that show how to remote start and remote control ArcGIS Pro from an ArcGIS Corehost application. This sample is comprised of two samples: Corehost server application that starts and controls the ArcGIS Pro client: ArcGISProConfigCoreHost ArcGIS Pro client application that is started and controlled: ArcGISProConfig To use the sample: 1. Make sure this project is available: "C:\Data\FeatureTest\FeatureTest.aprx" or change the path in the Corehost application. 1. Run the client application: ArcGISProConfigCoreHost 1. Note that the AppDomain is modified on startup to resolve the Assembly Paths for ArcGIS.Core.dll and ArcGIS.CoreHost.dll by using the ArcGIS Pro installation location. 1. The ArcGISProConfigCoreHost console application starts ArcGIS Pro with the "ArcGISProConfig" Managed Configuration Screen1.png 1. Once ArcGISProConfig has started and is ready, ArcGISProConfigCoreHost sends the project path: "C:\Data\FeatureTest\FeatureTest.aprx" to be opened 1. ArcGISProConfig opens the project Screen2.png 1. Once the output stops press any key to close the application. 1. Close the "ArcGISProConfig" client session (ArcGIS Pro) using the User Interface. Note that closing can be automated as well. 1. The "ArcGISProConfigCoreHost" Corehost application terminates after ArcGIS Pro has been closed. Screen3.png ... View more

Your code snippet doesn't change the FeatureLayer definition, instead it only reads it.   I found this snippet in our community samples that updates the labeling.  You can see how to update the layer definition (Esri/arcgis-pro-sdk-community-samples: ArcGIS Pro SDK for Microsoft .NET Framework Community Samples (github.com) ).: private async Task<CIMLabelClass> CreateAndApplyLabelClassAsync(FeatureLayer featureLayer, string oidField, List<long> oids) { var labelClass = await QueuedTask.Run(() => { var labelSelectedFeaturesWithLength = new CIMLabelClass { Name = "LabelSelectedFeaturesWithLength", ExpressionEngine = LabelExpressionEngine.Arcade, Expression = "$feature.MILES", WhereClause = $"{oidField} IN ({String.Join(", ", oids.ToArray())})", TextSymbol = SymbolFactory.Instance.ConstructTextSymbol().MakeSymbolReference(), Visibility = true }; var lyrDefn = featureLayer.GetDefinition() as CIMFeatureLayer; var listLabelClasses = lyrDefn.LabelClasses.ToList(); listLabelClasses.Add(labelSelectedFeaturesWithLength); lyrDefn.LabelClasses = listLabelClasses.ToArray(); featureLayer.SetDefinition(lyrDefn); return labelSelectedFeaturesWithLength; }); return labelClass; }   ...

Stephen, you can also use a pre-defined arrow symbol using this code:   if (_lineSymbol == null) { //Get all styles in the project var styleProjectItem2D = Project.Current.GetItems<StyleProjectItem>().FirstOrDefault(s => s.Name == "ArcGIS 2D"); await QueuedTask.Run(() => { //Get a specific project style by name var arrowLineSymbol = styleProjectItem2D.SearchSymbols(StyleItemType.LineSymbol, "Arrow Line 2 (Mid)")[0]; if (arrowLineSymbol == null) return; _lineSymbol = arrowLineSymbol.Symbol; }); }   The example symbology will look like this: Wolf_0-1663789107788.png I attached a sample tool code snippet that shows the symbology using a graphic overlay. EDIT: please substitute the SearchSymbol string using the following to get an arrow at the end: styleProjectItem2D.SearchSymbols(StyleItemType.LineSymbol, "Bold Arrow 2")[0];   Wolf_0-1663794606223.png   ...

I agree with Charlie, it appears that the Esri_Button style sets the MinWidth to 70.  So out-of-box the following XAML results in this UI representation: Wolf_0-1663366686347.png XAML:  <Button Grid.Column="1" HorizontalAlignment="Left" Style="{DynamicResource Esri_Button}" Command="{Binding OpenProjectCmd}" > <Image Source="Images\ArcGISProjectOpen16.png" Width="16" Height="16" /> </Button>  If you set the following Button tag attributes: 'MinWidth', 'MinHeight' and 'Padding' the Button's inner elements will determine the width/height: <Button Grid.Column="1" HorizontalAlignment="Left" MinWidth="0" MinHeight="0" Padding="0" Style="{DynamicResource Esri_Button}" Command="{Binding OpenProjectCmd}" > <Image Source="Images\ArcGISProjectOpen16.png" Width="16" Height="16" /> </Button> So now the UI looks like this: Wolf_1-1663367018477.png The reason why the Visual Studio XAML designer is not really WYSIWYG is because the XAML designer is not able to locate various Pro assemblies during design time, hence any ArcGIS Pro styles look different in the XAML designer versus when Pro is running. ...

To answer your question, it's important to know where SelectedOriginFeature.Feature is coming from.   There are multiple causes that can lead to this exception: Features can contain null or empty geometries, empty envelopes, and may optionally include geometries that are not simple this could lead to this error.   Also, it depends on how you populate your datagrid and then populate the 'Feature' property.   If you use a FeatureCursor as a returned by the Search method for example, you have to make sure that the cursor is not recycling.   The default for recycling is True, which can lead to this problem.   Search Method (Table)—ArcGIS Pro.   Having populated datagrids in the past i usually populate a custom class for each feature (added to an ObservableCollection) where i store the attribute data that i like to display.  If i have need for the geometry i use the Geometry's Clone method (when iterating through the cursor) to keep a copy of the geometry for later use.  This way i don't have to worry about recycling cursors etc.  Another way to avoid this problem is to retrieve the geometry only once you select a feature row using the object id (or global id).  Here is a sample that is doing just that:  Esri/arcgis-pro-sdk-community-samples: ArcGIS Pro SDK for Microsoft .NET Framework Community Samples (github.com) ...
