18.6 on Mac not working (50.4 KB)

Trying out the 18.6 .NET Core support.

Works on Windows but get PptxReadException when opening .pptx files on Mac.

PptxReadException: Input string was not in a correct format. (Presentation, Stream ,InterruptionToken)

FormatException: Input string was not in a correct format.
System.Number.StringToNumber(ReadOnlySpan str, NumberStyles options, ref NumberBuffer number, NumberFormatInfo info, bool parseDecimal)
System.Number.ParseInt64(ReadOnlySpan value, NumberStyles options, NumberFormatInfo numfmt)


I have observed the issue and request you to please try Aspose.Slides 18.5 on your end as well and share results. Please also provide source presentation and sample project for reference as well.

18.5 does not support .NET Core and can not be tested on Mac or Linux right?

To be clear. Attached slide works in 18.6 on Windows but NOT on Mac.


Aspose.Slides for ,NET 18.5 does not support .NET Core. However, it is still usable with Mono platforms. As requested earlier, please provide the sample project and environment details on your end so that we may perform testing on our end.

Attaching a sample project. (109.1 KB)

My environment:

macOS High Sierra 10.13.5 (17F77)
.NET Core 2.1 (SDK 2.1.301)
Visual Studio for Mac 7.5.3 (Build 7)
