Aspose.Slides for .NET 8 Compatibility in Docker Environment


Could you please let me know which version of Aspose Slides is compatible with .NET 8 in a docker environment. I have downloaded the latest version (Aspose.Slides for .NET 24.6 (DLLs only)) but it doesn’t have the .NET 8 dlls.


Thank you for contacting support.

Please read the following articles:
System Requirements|Aspose.Slides Documentation
Aspose.Slides for .NET 6 Cross Platform|Aspose.Slides Documentation

Please let us know if you have further questions after that.

Hi Andrey,
I am using latest version v24.6 of Aspose.Slides on my Alpine based docker container running .NET 8. While generating the PPT getting below exception. In .NET 6 this is working fine. Please assist.

We are sorry that you had to encounter this problem. Could you kindly share a simple project to reproduce the error on our end for further investigation?

Hi Andrey, thanks for checking this.

Unfortunately my organization doesn’t allow uploading source code to external url. Is there any other way I can help.

I saw a similar issue reported by another user and I think an issue with ID SLIDESNET-42911 was logged for that. Could you please provide me the resolution of that issue. Thanks.


You can try to isolate the problem and create an empty project with similar settings that reproduces the same error. We would be very grateful if you could share an example project.

The issue SLIDESNET-42911 is still open. Unfortunately, I don’t have any additional information yet.
