Reading barcodes and QR codes on the server side is a common requirement for document processing, inventory systems, and logistics applications. With the Dynamsoft Barcode Reader SDK and ASP.NET MVC 5 on .NET Framework 4.8 , you can add accurate, multi-format barcode decoding to a web application in a few focused steps. The SDK's CaptureVisionRouter API handles the heavy lifting on the backend, while a lightweight JavaScript frontend previews the image and draws color-coded overlays over every detected code. What you'll build: A responsive ASP.NET MVC 5 web application that accepts an uploaded image, decodes all barcodes and QR codes server-side using the Dynamsoft Barcode Reader SDK 11.4, and renders canvas overlays with format and text results in the browser.β¦
