For the attached sample file I found Presentation.GetThumbnails to hang when running a .NET Core app on Linux with Aspose.Slides 21.8. Hanging means I gave up after 5+ minutes and killed the process.

Hi @Andrey_Potapov - I wanted to check if you had an update regarding this issue. With version 21.10 I still observed that Presentation.GetThumbnails hangs.

Are you sure that the issue is resolved? I tested again with Aspose.Slides 21.12 and 22.1 and still saw that GetThumbnails was hanging with an embedded OLE object like in the presentation above.

Thank you for the additional information.
Aspose.Slides for .NET Core does not support System.Drawing.Common 6.0.0 yet. The latest supported version is 5.0.3. We are glad your issue has been resolved.
