IComparer.Compare() exception

Hello,

I have a problem with the Aspose.Words.DocumentBuilder class, maybe you can help me out. If I create a specific instance of DocumentBuilder and then try to save it into a PDF file, I get an ArgumentException error with the following message:

Unable to sort because the IComparer.Compare() method returns inconsistent results. Either a value does not compare equal to itself, or one value repeatedly compared to another value yields different results. IComparer: 'System.Collections.Comparer'.

This problem only arises when I am using .Net Framework 4.5. On version 4.0 (or lower) it works without problems.

I attached the excact source code and a screenshot with the ArgumentException message.

I use the latest Aspose.Words for.NET 2.0, file version 14.1.0.0, product version 2014.01.31. Thank you in advance for your help.

As soon as you get this simple application ready, we’ll start investigation into your issue and provide you more information.

Hello,


I attached a sample project. Just run it and you will see that it crashes at the end of Export procedure in Exporter class. Let me know if you need anything else. As I said: it works if the application is built for .Net 4.0 framework, but it doesn’t work if built for .Net 4.5. Regards,
