WPF高级任务栏
基本使用
因为任务栏是程序级别的，所以要在App.xaml中进行设置

在任务栏上右击
同样也可以使用C#来实现，在主窗口中设置

上面代码关闭软件后上次加入的列表还会存在，但是在点击新增后，之前添加的列表项会被清空，原因在于jumpList = new JumpList();这句代码。可以将jumpList进行序列化进行存储，每次打开存储的文件。

任务栏重叠图标
在已有任务栏图标上加上下图像，如开始暂停，来描述不同的状态。
taskBarItem.Overlay = new BitmapImage( new Uri("play.png"));
或者在xaml中设置Overlay<TaskbarItemInfo x:Name="taskBarInfo" Overlay="icon.png" >
本人在Win10下测试，没有效果，有知道原因的小伙伴在评论区说一下
缩略图按钮
鼠标悬浮在任务栏上，提供一种快速控制的方式。

缩略图裁剪
某些情况下，缩略图不需要显示整个窗口，只需要聚焦在窗口中的某一区域，则可以使用缩略图裁剪。
