    Syntax
    public class ProjectWindowSelectedItemsChangedEventArgs : System.EventArgs 
    Public Class ProjectWindowSelectedItemsChangedEventArgs 
       Inherits System.EventArgs
    Remarks
    Access the IProjectWindow to get the selection change for that window. There can be more than one project (view) pane open as well as the Project dockpane ("catalog"). Each will have its own selection.
    Example
    Geodatabase Content from Catalog selection
    // subscribe to event
    ProjectWindowSelectedItemsChangedEvent.Subscribe(async (ProjectWindowSelectedItemsChangedEventArgs args) =>
    {
      if (args.IProjectWindow.SelectionCount > 0)
      {
        // get the first selected item
        var selectedItem = args.IProjectWindow.SelectedItems.First();
