From the release of version 21.1.0.35 (2023 Volume 1) of Essential Studio, the Pdfium package has been upgraded to improve various functionalities like text search, text selection, rendering, and even performance. If you are updating your project to this version of the Syncfusion PDF Viewer, you may encounter the “Web-Service is not listening” error. The Network tab can help you identify the root cause of the issue, which is typically caused by an old version of pdfium assembly being referenced in the local web service project. Below are the assemblies to be referred to in the respective operating systems.

  • Windows – pdfium.dll
  • Linux – libpdfium.so
  • OSX – libpdfium.dylib
