If you would like to load data from Microsoft® Project® document files (.MPP) and present it using Gantt Chart Library for WPF or Project Management Library for WPF, you can use Aspose.Tasks components from Aspose (a third party ISV).
A sample application showing how you can perform this task (including commented C# source code) is available for download and further guidance: Project Document sample.
Note: In order to use the external Aspose.Tasks components you need a separate product license that you can purchase from Aspose. However, a 20% price discount applies if you have already purhcased a DlhSoft product usage license: to obtain the discount, please use ASPOSE4DLH promotional code when submitting the Aspose purchase request form.
