首先去https://www.bingmapsportal.com/申请一个免费的Key。

       CredentialsProvider  =“Key”

       ScaleVisibility   标尺

       ZoomBarVisibility  放大缩小

        Mode       模式切换（地图、卫星）

       Center  中心经纬度

       ZoomLevel   缩放水平 

       深入一点：

       一、加标记

       Pushpin 类

            Pushpin pin = new Pushpin();

            pin.Location = new System.Device.Location.GeoCoordinate(30.508, 114.393);               //  经纬度
            pin.Width = 120;
            pin.Height = 100;
            pin.Content = "我家住这儿！";
            pin.Background = new SolidColorBrush(Colors.Brown);

            myMap.Children.Add(pin);

       二、绘制多边形区域

       多边形、自动封闭MapPolygon类

            MapPolygon poly = new MapPolygon();
            poly.Fill = new SolidColorBrush(Colors.Purple);
            poly.Stroke = new SolidColorBrush(Colors.Red);
            poly.StrokeThickness = 8;
            poly.Opacity = 0.7;

            poly.Locations = new LocationCollection() {
                    new GeoCoordinate(30.508, 114.393),
                    new GeoCoordinate(30.5098, 114.3953),
                    new GeoCoordinate(30.5082, 114.3960),
                    new GeoCoordinate(30.5078, 114.3946)};
            myMap.Children.Add(poly);

       多边线（形）、不能自动封闭MapPolyline类

            MapPolyline polyline = new MapPolyline();
            polyline.Stroke = new SolidColorBrush(Colors.Red);
            polyline.StrokeThickness = 8;
            polyline.Opacity = 0.7;

            polyline.Locations = new LocationCollection() {
                    new GeoCoordinate(30.508, 114.393),
                    new GeoCoordinate(30.5083, 114.3916),
                    new GeoCoordinate(30.5045, 114.3916),
                    new GeoCoordinate(30.5059, 114.3954)};
            myMap.Children.Add(polyline);

        三、加图片

        MapLayer类 

            Image img = new Image();
            img.Width = 100;
            img.Height = 100;
            img.Source = new BitmapImage(new Uri("Lighthouse.jpg",UriKind.Relative));

            MapLayer mlayer = new MapLayer();
            mlayer.AddChild(img,new GeoCoordinate(30.5068,114.3939),PositionOrigin.BottomLeft);
            myMap.Children.Add(mlayer);
