create a Windows 10 notification using the Windows.UI.Notifications namespace and the ToastNotificationManager class. 

the CreateNotification() method takes two string arguments: title, which is the title of the notification, and message, which is the message body of the notification. The ToastNotificationManager is used to create a ToastNotifier instance, which is used to display the notification. The GetTemplateContent() method is used to obtain an XML document that defines the notification layout, and the GetElementsByTagName() method is used to obtain a list of the elements in the document. The text of these elements is then set to the specified title and message using the CreateTextNode() method. A new ToastNotification instance is then created using the modified XML document, and the Show() method of the ToastNotifier is used to display the notification for 10 seconds (ExpirationTime property).

The resulting output is a message indicating that the notification has been created successfully. Note that displaying a Windows 10 notification may require appropriate system permissions, and that you should use caution and appropriate security measures when working with system-level functions.
