I am receiving an exception while trying to render an
<ul>list.The exeption: Method not found: 'QuestPDF.Infrastructure.IContainer QuestPDF.Fluent.ElementExtensions.Element(!!0, System.Func`2<QuestPDF.Infrastructure.IContainer,QuestPDF.Infrastructure.IContainer>)'.
Example content:
If I omit the
<ul>tag the PDF is generated successfully. I also tried the same content with the HTMLToQPDF.Example.exe downloaded from the project page and it works. Is there something I am missing?
