I use mapsui control in WPF to show on the map 4 lines between 5 points. I implemented a method that shows the selected line by clicking on the map. Now I need to be able to select all 4 lines at the same time. It would be preferable that when the cursor is dragged, a polygon is formed and all the lines in them are selected. How could I implement such a method with Mapsui Control? Unfortunately I can’t find this information in the mapsui documentation on the site.

 public Task<Map> CreateMapAsync(Map map)
        {
            map.Layers.Add(Mapsui.Tiling.OpenStreetMap.CreateTileLayer());
            var polylineLayer = CreatePolylineLayer();
            map.Layers.Add(polylineLayer);
            map.Navigator.CenterOnAndZoomTo(polylineLayer.Extent!.Centroid, map.Navigator.Resolutions[6]);
            map.Info += (s, a) => ToggleSelected(a.MapInfo?.Feature);
            map.Widgets.Add(new MapInfoWidget(map));
            return Task.FromResult(map);
        }

        public static ILayer CreatePolylineLayer()
        {
            return new Layer("Polyline")
            {
                DataSource = new MemoryProvider(CreatePolylines(CreatePoinst()).Select(p => new GeometryFeature { Geometry = p })),
                Style = CreateLineStringStyle(),
                IsMapInfoLayer = true
            };
        }

 private static List<Point> CreatePoinst()
 {
     var berlin = new Point(13.4050, 52.52);
     var dresden = new Point(13.7373, 51.0504);
     var leipzig = new Point(12.3712900, 51.33962);
     var stuttgard = new Point(9.1829321, 48.7758459);
     var hannover = new Point(9.7332, 52.3705);
     List<Point> points = new List<Point>() { berlin, dresden, leipzig, stuttgard, hannover };
     return points;
 }

 private static List<LineString> CreatePolylines(List<Point> points)
 {
     List<LineString> ListPolylines = new List<LineString>();
     for (int i = 0; i < points.Count-1; i++)
     {
         var netTopSu = NetTopologySuite.NtsGeometryServices.Instance.CreateGeometryFactory(4326);
         var lnsAURtoLER = netTopSu.CreateLineString(new[] {
                     new NetTopologySuite.Geometries.Coordinate(points[i].Y, points[i].X),
                     new NetTopologySuite.Geometries.Coordinate(points[i+1].Y, points[i+1].X)});
         var stringOfGeometry = lnsAURtoLER.ToString();
         var lineString = (LineString)new WKTReader().Read(stringOfGeometry);
         lineString = new LineString(lineString.Coordinates.Select(v => SphericalMercator.FromLonLat(v.Y, v.X).ToCoordinate()).ToArray());
         ListPolylines.Add(lineString);
     }
     return ListPolylines;
 }

   public static IStyle CreateLineStringStyle()
        {
            return new ThemeStyle(f =>
            {
                if (f["selected"]?.ToString().Length > 0 ) //f["selected"]?.ToString() == "true"

                    return new VectorStyle
                    {
                        Fill = null,
                        Outline = null,
                        Line = { Color = Mapsui.Styles.Color.Blue, Width = 4 }
                    };
                return new VectorStyle { Fill = null, Outline = null, Line = { Color = Mapsui.Styles.Color.Red, Width = 5 } };
            });
        }```
