3. Exit the application
4. Observe the performance of the corresponding process in the Task Manager (or mount the Visual Studio debugger to view)

--------------------------

1. 创建一个空白 WinUI 3 应用
2. 挂载 PackageCatalog.PackageUpdating 事件
3. 退出应用
4. 看任务管理器对应进程的表现（或挂载 Visual Studio 调试器查看）

Expected behavior
