15

@sullivan,
As far as I can see, we still have some issues with including the fix in releases of Aspose.Slides. I have again requested information from our developers for you.

@sullivan,
Unfortunately, the NameOfApplication cannot be changed. This is a standard limitation in all Aspose products that generate documents with similar properties.

17

Aspose.Slides provides an API to modify NameOfApplication, but the modification does not take effect,So it must be abnormal.
You’d better check again, Others such as Aspose.PDF/Aspose.Words/Aspose.Cells don’t have this problem.

pptDocument.DocumentProperties.NameOfApplication = "My Application";

@sullivan,
According to the information I have (Aspose policy), this should not be the case. Thank you for reporting this. We will discuss this issue.

@sullivan,
Please look at the API Limitations of Aspose.Slides for .NET. Aspose has long had a policy that does not allow changing some fields of document metadata, this is written in the documentation and we cannot change this behavior. In Aspose.Cells and Aspose.Words, the behavior was implemented prior to this policy and was left for backward compatibility. We apologize for not giving a clear answer for a long time, we will improve the documentation, API Reference, and API. Thank you for your patience.
