I am using Aspose.Cells to export excel functionality from html string in .Net 6, it is working fine the first time downloading a file but if I try a second time to download it is getting an error as below.

Our project is container image based and Linux server.

Error :Unhandled exception. System.TypeInitializationException: The type initializer for ‘SkiaSharp.SKObject’ threw an exception.

System.DllNotFoundException: Unable to load shared library ‘libSkiaSharp’ or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: Error loading shared library liblibSkiaSharp: No such file or directory,at SkiaSharp.SkiaApi.sk_version_get_milestone()at SkiaSharp.SkiaSharpVersion.get_Native()

My current Version : Aspose.cells 22.12.0

Please reply as soon as possible.

Thanks

@riyazahamedj0101,

We recommend using newer versions to work on .NET6.0 for non Windows os. Aspose.Cells now also provides .NET6.0 library that uses SkiaSharp as the graphics library, as recommended in official statement of Microsoft. For more details about using Aspose.Cells with NET6, please see the documents.

Please try using our latest version/fix: Aspose.Cells for .NET v23.3 (Releases | NuGet).

In case you still find the issue, kindly do provide a sample project to reproduce the issue, we will check it soon.

It is strange that it works OK for the first time, but throws such initialization exception for the second time.

Could you please share us a sample project with docker file to reproduce the issue?
