      <script type="text/javascript">
          // set the session identifier
          Vintasoft.Shared.WebImagingEnviromentJS.set_SessionId("SessionID");
  
          // specify web services, which should be used by Vintasoft Web Document Viewer
          Vintasoft.Shared.WebServiceJS.defaultFileService =
              new Vintasoft.Shared.WebServiceControllerJS("vintasoft/api/MyVintasoftFileApi");
          Vintasoft.Shared.WebServiceJS.defaultImageCollectionService =
              new Vintasoft.Shared.WebServiceControllerJS("vintasoft/api/MyVintasoftImageCollectionApi");
          Vintasoft.Shared.WebServiceJS.defaultImageService =
              new Vintasoft.Shared.WebServiceControllerJS("vintasoft/api/MyVintasoftImageApi");
  
          // create thumbnail viewer
          var thumbnailViewer = new Vintasoft.Imaging.UI.WebThumbnailViewerJS("WebThumbnailViewer1Div");
          // create image viewer
          var imageViewer = new Vintasoft.Imaging.UI.WebImageViewerJS("WebImageViewer1Div");
          // specify that image viewer depends from thumbnail viewer
          imageViewer.set_MasterViewer(thumbnailViewer);
  
          // open file from session folder and add images from file to the image viewer
          imageViewer.get_Images().openFile("VintasoftImagingDemo.pdf");
      </script>
  </body>
  </html>
  
  

Run the ASP.NET MVC5 application and see the result.
