Retrieves all TaskPriorities defined within your Workspace.
A TaskPriority is a named priority level used by your business to determine how to decide which Tasks are the most important. You can name your TaskPriority levels anything you like and you can reorganize the order of the TaskPriority levels at any time.
Note that TaskPriority and ProjectPriority are different classes of priority levels. Even if they may have similar names, they are different objects and must be tracked separately.
See TaskPriorityDto for the complete data definition.
