When trying to convert XML to PDF, I do this

PdfDocument pdfDocument = new PdfDocument();
HtmlToPdf.ConvertHtml(xml, pdfDocument);

where xml is a string.

I run it in Visual Studio, in a project targetting .NET 5.0
running on a pc running Windows 10 Enterprise version 20H2.

I get this error

EO.Pdf.HtmlToPdfException: 'Conversion failed. System.Drawing.Common is not supported on this platform.'

InnerException:
PlatformNotSupportedException: System.Drawing.Common is not supported on this platform.
This exception was originally thrown at this call stack:
System.Drawing.Drawing2D.Matrix.Matrix(float, float, float, float, float, float)
EO.Pdf.Drawing.PdfMatrix.implicit operator System.Drawing.Drawing2D.Matrix(EO.Pdf.Drawing.PdfMatrix)
EO.Pdf.Drawing.PdfMatrix.Translate(float, float)
EO.Pdf.PdfDocument.wmao.ouoa(EO.Pdf.PdfPage, EO.Internal.ayvo, float?, bool)
EO.Pdf.PdfDocument.wmao.lbel(EO.Internal.ayvo, int)
EO.Pdf.PdfDocument.wmao.spbn()
EO.Internal.ayli.spbo(EO.Pdf.HtmlToPdfResult, EO.Pdf.PdfDocument, int)
EO.Internal.ayli.spbn(EO.Internal.aylj)

This, on the other hand, works:
HtmlToPdf.ConvertUrl(inputPath, outputPath);
