Using ExecuteCommandArgs to open a dock pane empties the DockpaneManager object, not allowing it to to open any dock pane in ArcGIS Pro SDK for .NET.

Do not use the QueuedTask to open the dock pane. It has to be opened on the UI thread. Try this instead: protected override Func ExecuteCommandArgs(string id) { try { ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show($"message: {id}"); // Run the command specified by the id passed into ExecuteCommandArgs IPlugInWrapper wrapper = FrameworkApplication.GetPlugInWrapper(id); var command = wrapper as ICommand; if (command != null && command.CanExecute(null)) command.Execute(null); } catch (System.Exception e) { ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show($"ERROR: {e}", "Error running command"); } return (object[] args) => DoNothing(); } private Task DoNothing() { return Task.CompletedTask; }
