How to send visio changes (like adding new shapes) to server for save purpose on the server side?
your demo does not seem to have any save functionality: https://products.aspose.app/diagram/en/editor
I have downloaded the github demo, and it does not have save functionality at all.
I kinda leveraged the export code from the github demo code. In export, VsdxService is used to add pages, and then zip. But this saves the changes into file with a zip version. That when the problem starts, when I try to open the saved file within a visio app, it does not open.
