Hi Steve,
Thank you for writing to Aspose support team.
We have verified the exception while loading the sample MPP file with the latest version of Aspose.Tasks for .NET and have logged it as TASKS-34329 in our bug tracking system. Our development team will investigate the issue further. Usually, issues are fixed in the upcoming release of the API, however, it may take extra time if there is some complexity involved. In any case, we’ll update you here once there is some information available about this issue.
The issues you have found earlier (filed as TASKS-34329) have been fixed in this update.
