Convert HTML string to PDF throws exception

I have a valid html string that I generated to .html file and viewed in the browser. the code is as follows:

        string htmlStr = "<html>" +
            "               <head> " +
            "                   <meta charset='utf-8'/>" +
            "                   <meta name='viewport' content='width=device-width, initial-scale=1.0' />" +
            "               </head> " +
            "               <body style=\"width:1001px;height:600px;margin-left:auto;margin-right:auto;\">" +
            "                   <div id='badgefront' style='width:500px;height:250px;float:left;text-align:center;font-weight:bold;font-size:20px;border-right:1px black dashed;background-color:#CCC4C0;'>" +
            "                       <p>XXXX</p>" +
            "                       <img src='..\\..\\..\\wwwroot\\data\\vme.jpg' alt='VME' height='150' width='150'> " +
            "                   </div>" +
            "                   <div id='badgeback' style='width:500px;height:250px;float:right;left;text-align:center;font-weight:bold;font-size:20px;background-color:#CCC4C0;'>" +
            "                       <p>URL: XXXXX</p> " +
    "                               <img src='..\\BarCode\\tmpBarcode-0.bmp' alt='barcode' height='125' width='400'> " +
    "                                <p>XXXXXX</p>" +
            "                   </div>" +
            "               </body>" +
            "               </html>";

After creating the string I execute the following commands:

        Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document();
        Aspose.Pdf.HtmlFragment textFragment = new Aspose.Pdf.HtmlFragment(htmlStr);
        // Save output as PDF format
        pdfDocument.Save(filePath + "WebpageToPdf.pdf");

Using the ‘HtmlFragment’ I get the following error:

An exception of type ‘System.IO.FileNotFoundException’ occurred in Aspose.Pdf.dll but was not handled in user code
Could not load file or assembly ‘System.Windows.Forms, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089’. The system cannot find the file specified.

If I change the ‘HtmlFragment’ to ‘TextFragment’, it will write the code to the the PDF file but not render it.

This is running in C# .Net Core 2. If you need additional information, please let me know!

Thank you,
