While on Windows® Forms platform DlhSoft Gantt Chart Library 2.0 and Project Management Library 2.0 are entirely different products (from goals and architectural design to their actual features), on WPF we have always had Gantt Chart Library (GCL) 4.0 and 3.1 being just subsets of Project Management Library (PML) 4.0 and 3.1, accordingly.
Actually, the WPF chart controls (*Chart*View) that were included by a PML license were also available with a GCL license at a slightly lower price. For example, the cost for a Personal License for PML was 749 €, while a similar GCL license has had a cost of 699 €, and both licenses included GanttChartView, GanttChartTaskListView, ScheduleChartView, ScheduleChartResourceListView, LoadChartView, and LoadChartResourceListView controls; of course, the PML license provided supplemental access to non-chart visualizations like TaskListView, ResourceListView and (the very interesting, in our opinion) ScheduleDefinitionView.
On the other hand, we also have the separate DlhSoft Gantt Chart Light Library (GCLL) for Silverlight™ and WPF available, including similar Gantt Chart enabled components, such as GanttChartView, GanttChartDataGrid, ScheduleChartView, ScheduleChartDataGrid, LoadChartView, and LoadChartDataGrid, redesigned from scratch and developed to obtain the highest possible runtime performance.
Are you confused? Don’t worry (anymore). We recently decided that it’s time to do something to limit confusion, while keeping everybody happy, tough:
- We discontinued GCL 4.0/3.1 for WPF 4/3.5, as they were just subsets of PML versions that continue to be available, and also as developers often requested moving from GCL to GCLL to achieve better performance for their Gantt Chart enabled WPF applications (our GCL page URL on our Web site redirects to GCLL now);
- We lowered down the prices for PML for WPF licenses to the same amounts as we have had for GCL; in other words, if you pay the lower price of the previously available subset product (GCL), now you get all the components of the original superset (PML);
- Existing GCL for WPF licensees are assumed to be PML licensees upon new order requests, so they can renew and upgrade their licenses as if they would have originally ordered the PML product;
- We have kept other products, such as GCL 2.0 and PML 2.0 for Windows Forms®, and also the recommended GCLL for Silverlight™ and WPF completely unchanged.
