I use Aspose to convert VSD -> VSDX. I found two files which cannot be open by visio after convertion. Here is a sample application:
VisioTest.zip (862.3 KB)
Steps to reproduce:
- Open project in Visual Studio
- In MainWindow constructor set a license for Aspose (important!)
- Run the app, choose a destination folder and press button. You will find in this folder two files.
- Try to open them in Visio
If you need more info, please let me know
Thanks
