[.Net] Diagram.Save exception after CopyTheme

@itklondike,

Kindly send us all details of the scenario, including source Visio drawing, stencil file (if any) and code. We will investigate your scenario in our environment and share our findings with you.

Hi, basically any Visio 2016 diagram fails. I’ve just created a new one from scratch with a rectangle and ran the code from Aspose git examples. Just run CopyShape.Run();

Unfortunately can’t attach the visio file due to forum restrictions. Do you have any e-mail so I can send the file?Drawing1.zip (15.2 KB)

UPD. Attached the file
