    Exceptions
    ExceptionDescription
    This method must be called within the lambda passed to QueuedTask.Run
    Example
    How to construct a point symbol from a marker
    await QueuedTask.Run(() =>
    {
      CIMMarker marker = SymbolFactory.Instance.ConstructMarker(ColorFactory.Instance.GreenRGB, 8.0, SimpleMarkerStyle.Pushpin);
      CIMPointSymbol pointSymbolFromMarker = SymbolFactory.Instance.ConstructPointSymbol(marker);
    });
    How to construct a multilayer line symbol with circle markers on the line ends
    //These methods must be called within the lambda passed to QueuedTask.Run
    var lineStrokeRed = SymbolFactory.Instance.ConstructStroke(ColorFactory.Instance.RedRGB, 4.0);
    var markerCircle = SymbolFactory.Instance.ConstructMarker(ColorFactory.Instance.RedRGB, 12, SimpleMarkerStyle.Circle);
    markerCircle.MarkerPlacement = new CIMMarkerPlacementOnVertices()
    {
      AngleToLine = true,
      PlaceOnEndPoints = true,
      Offset = 0
    };
    var lineSymbolWithCircles = new CIMLineSymbol()
    {
      SymbolLayers = new CIMSymbolLayer[2] { markerCircle, lineStrokeRed }
    };
    
    How to construct a multilayer line symbol with an arrow head on the end
    //These methods must be called within the lambda passed to QueuedTask.Run
    var markerTriangle = SymbolFactory.Instance.ConstructMarker(ColorFactory.Instance.RedRGB, 12, SimpleMarkerStyle.Triangle);
    markerTriangle.Rotation = -90; // or -90
    markerTriangle.MarkerPlacement = new CIMMarkerPlacementOnLine() { AngleToLine = true, RelativeTo = PlacementOnLineRelativeTo.LineEnd };
    
    var lineSymbolWithArrow = new CIMLineSymbol()
    {
      SymbolLayers = new CIMSymbolLayer[2] { markerTriangle,
                  SymbolFactory.Instance.ConstructStroke(ColorFactory.Instance.RedRGB, 2)
              }
    };
