Step 3: Configure your application and click Create.

Step 4: Install the Syncfusion.HtmlToPdfConverter.Net.Mac NuGet package as reference to your .NET Standard applications from NuGet.org.

NOTE

Starting with v16.2.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects.

C#

@{Html.BeginForm("ExportToPDF", "Home", FormMethod.Post);
    {
        <div>
            <input type="submit" value="Convert PDF" style="width:150px;height:27px" />

    HtmlToPdfConverter htmlConverter = new HtmlToPdfConverter();
    //Convert URL to PDF.
    PdfDocument document = htmlConverter.Convert("https://www.syncfusion.com");
    MemoryStream stream = new MemoryStream();
    document.Save(stream);
    //Download the PDF document in the browser
    return File(stream.ToArray(), System.Net.Mime.MediaTypeNames.Application.Pdf, "HTML-to-PDF.pdf");
}

Step 8: Right click the project and select Build.
