Maximum time interval duration within Gantt Chart Library and Project Management Library for WPF

Is there a maximum time interval duration value (used for example, as the maximum task duration) within Gantt Chart Library for WPF or Project Management Library for WPF?

Yes, to improve performance, such a maximum duration values is defined within the Schedule object instances. By default it is set to about 2 years (730.5 days), but it can be modified by inheriting from the Schedule class, overriding the GetDefaultMaxSearchDuration method, and setting such custom schedule instances to DlhSoft components.
