Blazor PDF Viewer Sample (WebViewer)

WebViewer is a powerful JavaScript-based PDF Library that's part of the PDFTron PDF SDK. It provides a slick out-of-the-box responsive UI that interacts with the core library to view, annotate and manipulate PDFs that can be embedded into any web project.

This repo is specifically designed for any users interested in integrating WebViewer into a Blazor project. This project was integrated using the Blazor server-sided application template.
