A User Activity encapsulates a user's task that can be continued at a later time. Creating a User Activity causes that activity to appear in Windows Timeline and in Cortana's Pick up where I left off feature. Timeline is a rich task view that shows a chronological view of what you’ve been working on. It can also include what you were working on across devices. For example, a mail app could create a User Activity when the user starts creating a new email message. The user could pause working on the email and then work on it later on the same machine, or even another device.
An application must never create this object directly. Instead of that an application must use TwclTimelineChannel component to create or get an User Activity objects.
The User Activity is supported on Windows 10 16299 and above.
