Project reading exception while reading MPP files


Hello Team,
I am getting following exception for reading mpp files with Aspose.Task.dll.

Aspose.Tasks for .NET version. Reading project data in ‘MPP14’ format, created by ‘MSP2016’ started.
Aspose.Tasks.TasksReadingException: Project reading exception. —> System.ArgumentException: An entry with the same key already exists.

Please suggest solution.

Thanks & Regards,



I have observed that you are using fairly old API version. I suggest you to please try using latest Aspose.Tasks for .NET 19.5 on your end. In case there is still an issue, please share source file along with used sample code reproducing issue.
