How to load a document that contains fundamental syntax errors.

In the WPF PDF Viewer, documents containing minor syntax errors can be successfully opened using the Open and Repair feature provided by the PdfLoadedDocument object.

Steps to Load a PDF that contains fundamental syntax errors

Step 1: In the button click event handler, create an OpenFileDialog object that allows users to select only PDF files.

     var dialog = new OpenFileDialog
     {
         Filter = "PDF files (*.pdf)|*.pdf",
         InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Desktop),
     };
     if (dialog.ShowDialog() == true)
     {
         LoadPdfFile(dialog.FileName);
     }

Step 2: Open the selected PDF document from the OpenFileDialog using the OpenAndRepair overloads of the PdfLoadedDocument. To address the basic syntax error, pass true to the OpenAndRepair parameter of the overload.

   //Repair the PDF document with basic syntax errors
   pdfDocument = new PdfLoadedDocument(new FileStream(value, FileMode.Open, FileAccess.Read, FileShare.ReadWrite), true);
   pdfViewer.Load(pdfDocument);

A complete working sample to handle the document with basic syntax errors can be downloaded from GitHub.
