    Remarks
    All elements on a layout must have a unique name so they can be easily referenced.
    Example
    Element_SetName
    //Modify an element's name.
    
    //Perform on the worker thread
    await QueuedTask.Run(() =>
    {
      element.SetName("New Name");
    });
    Create Legend 2
    //Must be on QueuedTask.Run(() => { ...
    
    //Build geometry
    Coordinate2D ll = new Coordinate2D(6, 2.5);
    Coordinate2D ur = new Coordinate2D(8, 4.5);
    Envelope env = EnvelopeBuilderEx.CreateEnvelope(ll, ur);
    
    //Reference MF, create legend and add to layout
    MapFrame mf = layout.FindElement(mapFrameName) as MapFrame;
    var surroundInfo = new LegendInfo()
    {
      MapFrameName = mf.Name
    };
    
    var legendElm = ElementFactory.Instance.CreateMapSurroundElement(
      layout, env.Center, surroundInfo) as Legend;
    legendElm.SetName("New Legend");
    Create North Arrow From StyleItem 2
    //Must be on QueuedTask.Run(() => { ...
    
    //Build geometry
    Coordinate2D center = new Coordinate2D(7, 5.5);
    
    //Reference a North Arrow in a style
    StyleProjectItem stylePrjItm = Project.Current.GetItems<StyleProjectItem>()
                                   .FirstOrDefault(item => item.Name == "ArcGIS 2D");
    NorthArrowStyleItem naStyleItm = stylePrjItm.SearchNorthArrows(
                                           "ArcGIS North 10")[0];
    
    //Reference MF, create north arrow and add to layout 
    //var mf = container.FindElement("New Map Frame") as MapFrame;
    var mf = layout.FindElement(MapFrameName) as MapFrame;
    var narrow_info = new NorthArrowInfo()
    {
      MapFrameName = mf.Name,
      NorthArrowStyleItem = naStyleItm
    };
    var arrowElm = (NorthArrow)ElementFactory.Instance.CreateMapSurroundElement(
      layout, center.ToMapPoint(), narrow_info) as NorthArrow;
    arrowElm.SetName("New North Arrow");
    arrowElm.SetHeight(1.75);
    arrowElm.SetX(7);
    arrowElm.SetY(6);
    Update element properties
    //Update an element's properties.
    
    //Performed on worker thread
    QueuedTask.Run(() =>
    {
      // update an element's name
      element.SetName("New Name");
    
      // update and element's visibility
      element.SetVisible(true);
    });
