Hi Pranav,
Thank you for contacting Syncfusion support.
Our PDF Viewer web service project will be supported in both Windows and Linux platform. For working in Windows environment we need to install the Syncfusion.EJ2.PdfViewer.AspNet.Core.Windows package in your project and then build and run the same. Similarly to work with Linux platform you need to install Syncfusion.EJ2.PdfViewer.AspNet.Core.Linux package in your project and the build and run it.
Note: Kindly do not install both the packages at a time in your project, which will throw errors.
Please revert us if you have any concerns on this.
Regards,
Akshaya
