T:Windows.ApplicationModel.UserActivities.UserActivity |
winrt class |
A UserActivity is created by an app during its execution to notify the system of a user work stream that can be continued on another device, or at another time on the same device. It provides information about a task the user is engaged in.
Note
Starting in July 2021, users who have activity history synced across their Windows devices through their Microsoft Account (MSA) will no longer have the option to upload new activity in Timeline. They'll still be able to use Timeline and see their activity history (information about recent apps, websites and files) on their local PC. AAD-connected accounts won't be impacted.

A UserActivity encapsulates a user's task that can be continued at a later time, and potentially on a different device. Creating a User Activity causes that activity to be capable of appearing 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, via activities that Windows believes to have had significant user engagement. It can also include what you were working on across devices. For example, a mail app could create a UserActivity 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.
