I am using Aspose v18.12.
When opening a MS Project file and saving, dates appear in the saved copy that did not exist in the original copy.
var stream = new FileStream(filePath, FileMode.OpenOrCreate); var project = new Project(stream, new LoadOptions()); project.Save(newfilePath, SaveFileFormat.MPP);
The before and after files can be compared in MS Project.
