When I process a project file in task usage view format, it will create new task called unassigned underneath each task. If there’s task with start/end date, the newly created unassigned task will then use it as its start and end date. If there’s any task with start/end date, it will then use current date.
I tested with Tasks C# v19.10.
Here’s my sample code and test file:
