Install Syncfusion.DocToPdfConverter.WinForms NuGet package

NOTE

  1. The Syncfusion.DocToPdfConverter.WinForms is a dependency for Syncfusion Windows Forms GUI controls and is named with the suffix “WinForms”. It contains platform-independent .NET Framework assemblies (compatible with versions 4.0, 4.5, 4.5.1, and 4.6) for the Word library and does not include any Windows Forms-related references or code. Therefore, we recommend using this package for .NET Framework Console applications.
  2. 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. Please refer to this link to know about registering Syncfusion license key in your application to use our components.

Step 3: Include the following namespaces in Program.cs file.

using Syncfusion.DocIO.DLS;

    using (DocToPDFConverter converter = new DocToPDFConverter())
    {
        //Convert Word document into PDF document.
        using (PdfDocument pdfDocument = converter.ConvertToPDF(document))
        {
            //Save the PDF document.
