If you don't want the service layer credits to show up on your map you can place them anywhere on your layout as a text element.  You can do this via the ArcGIS Pro UI or programmatically: String slcText = "<dyn type='layout' name='SLCs' property='serviceLayerCredits'/>"; GraphicElement slcTxtElm = ElementFactory.Instance.CreateTextGraphicElement(layout, TextType.RectangleParagraph, slcEnv, arial8reg, slcText); ...

I fixed your snippet above.   I guess the main issue was that the  CancelableProgressor parameter for ExecuteToolAsync is missing. protected override async void OnClick() { var done = await ProcessSpatialJoin(@"Crimes", @"Portland Precincts", @"C:\Data\Interacting with Maps\Interacting with Maps.gdb\Crimes_SpatialJoin", "50 Yards"); MessageBox.Show($@"Process done: {done}"); } public static async Task<bool> ProcessSpatialJoin(string target_feats, string join_feats, string output_feats, string search_radius) { //https://pro.arcgis.com/en/pro-app/latest/sdk/api-reference/topic10957.html var progDlg = new ProgressDialog("Running spatial join", "Cancel"); progDlg.Show(); var progsrc=new CancelableProgressorSource(progDlg); //System.Windows.MessageBox.Show("Progress bar show"); var environments = Geoprocessing.MakeEnvironmentArray(overwriteoutput: true); var parameters = await QueuedTask.Run(() => { var join_operation = "JOIN_ONE_TO_ONE"; var match_option = "INTERSECT"; var field_map = ""; return Geoprocessing.MakeValueArray(target_feats, join_feats, output_feats, join_operation, "KEEP_COMMON", field_map, match_option, search_radius); }); GPExecuteToolFlags flags = GPExecuteToolFlags.AddOutputsToMap | GPExecuteToolFlags.GPThread | GPExecuteToolFlags.AddToHistory; var toolResult = await Geoprocessing.ExecuteToolAsync("SpatialJoin_analysis", parameters, environments, progsrc.CancellationTokenSource.Token, null, flags); //// dialog hides itself once the execution is complete //progDlg.Hide(); //System.Windows.MessageBox.Show("Progress bar hide"); if (toolResult.IsFailed == true) { Geoprocessing.ShowMessageBox(toolResult.Messages, "GP Messages", toolResult.IsFailed ? GPMessageBoxStyle.Error : GPMessageBoxStyle.Default); } return !(toolResult.IsFailed); } I tried with release 3.0 as well and it worked with 3.0 too:   ... View more

I actually tried to create an Add-in sample that writes an XML file using ClosedXML and was not able to get it to work properly.   After some testing it turns out that one of the dependencies of ClosedXML is DocumentFormat.OpenXML which is already included with ArcGIS Pro in the ArcGIS Pro bin folder.   I was unable to find a matching release of ClosedXML, so i wrote my sample using DocumentFormat.OpenXML instead.  The trick here is that you have to reference the DocumentFormat.OpenXML.dll file in the ArcGIS Pro bin folder and to NOT include the DocumentFormat.OpenXML NuGet.  Using the NuGet might lead to another version mismatch.  Also when including the OpenXML reference make sure that no specific version is listed and the copy local setting is false.    I attached my sample project.     ...

If you implement your checkbox logic in the viewmodel as @GKmieliauskas  suggests you have to prevent recursion when you set the counter property.  Here is my suggestion (i attached a sample solution) private bool _isCheckedOne; private bool _isCheckedTwo; public bool IsCheckedOne { get { return _isCheckedOne; } set { SetProperty(ref _isCheckedOne, value); if (IsCheckedTwo == IsCheckedOne) { // prevent recursion IsCheckedTwo = !IsCheckedOne; } } } public bool IsCheckedTwo { get { return _isCheckedTwo; } set { SetProperty(ref _isCheckedTwo, value); if (IsCheckedOne == IsCheckedTwo) { // prevent recursion IsCheckedOne = !IsCheckedTwo; } } } ...

You can use this snippet to delete all data from a layer: var theFeatureLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault(); if (theFeatureLayer == null) { MessageBox.Show("Unable to find a FeatureLayer in the Table of Content"); return; } QueuedTask.Run(() => { theFeatureLayer.GetTable().DeleteRows(new QueryFilter () ); }); and the code to copy data from one layer to another is included in the code above. // copy some data await QueuedTask.Run(() => { // create an edit operation EditOperation copyOperation = new EditOperation() { Name = "Copy Data", ProgressMessage = "Working...", CancelMessage = "Operation canceled.", ErrorMessage = "Error copying polygons", SelectModifiedFeatures = false, SelectNewFeatures = false }; using var rowCursor = originalLayer.Search(); while (rowCursor.MoveNext()) { using (var row = rowCursor.Current as Feature) { var geom = row.GetShape().Clone(); if (geom == null) continue; var newAttributes = new Dictionary<string, object> { { "field1", 1.0 }, { "field2", 2.0 } }; copyOperation.Create(newLyr, geom, newAttributes); } } // execute the operation onoy if changes where made if (!copyOperation.IsEmpty && !copyOperation.Execute()) { MessageBox.Show($@"Copy operation failed {copyOperation.ErrorMessage}"); return; } }); // check for edits if (Project.Current.HasEdits) { var saveEdits = MessageBox.Show("Save edits?", "Save Edits?", System.Windows.MessageBoxButton.YesNoCancel); if (saveEdits == System.Windows.MessageBoxResult.Cancel) return; else if (saveEdits == System.Windows.MessageBoxResult.No) _ = Project.Current.DiscardEditsAsync(); else { _ = Project.Current.SaveEditsAsync(); } } ...
