Previously, we published a GitHub repository named blazor-barcode-qrcode-reader-scanner, showcasing the development of a web barcode reader using Blazor WebAssembly. In this project, C# accounted for only 2.0% of the entire codebase, mainly tasked with invoking JavaScript code. The core functionality was primarily implemented in JavaScript. With an aim to enhance...

Last week, we developed a RESTful service using .NET C# and Twain.Wia.Sane.Scanner library to scan documents from TWAIN, WIA, SANE, and eSCL scanners. This week, we will repurpose the C# code to construct a Blazor WebAssembly application that digitizes documents directly from a web browser, all without the need for...

RESTful service can be accessed from anywhere with an internet connection, irrespective of platform or device. Deploying a commercial SDK as a RESTful service can simplify integration, improve accessibility, and provide better control over the deployment environment and usage. In this article, we’ll delve into how you can effortlessly integrate...

Having previously developed libraries for Node.js, Flutter, Java, and Python to integrate with Dynamsoft Service’s REST API, we’re now turning our attention to .NET. In this article, we introduce a .NET library to interface with the REST API, facilitating document scanning from TWAIN, WIA, SANE, and eSCL compatible scanners. We’ll...

Web and mobile app development has drawn most of the attention in recent years, but desktop apps still play a critical role in our productivity. The Windows UI Library (WinUI) is a native user experience (UX) framework for both Windows desktop and UWP applications. It is Microsoft’s latest technology to...

If you are a .NET developer, you might consider using Blazor for web development, as it allows you to write web apps using C# and HTML. A significant advantage of Blazor is its ability to reuse existing .NET libraries and open-source C# code. However, using Blazor doesn’t mean you can...

Dynamsoft’s Capture Vision SDKs consist of the Dynamsoft Document Normalizer, Dynamsoft Barcode Reader, and Dynamsoft Label Recognizer. All of these SDKs are cross-platform, supporting Windows, Linux, Android, iOS and web. Each vision SDK can be used independently or in combination with others. In this article, we’ll show you how to...

ASP.NET Core is a cross-platform, high-performance, open-source framework for building modern, cloud-enabled, Internet-connected apps. It is convenient to use it to build web APIs and web apps. In this article, we are going to talk about how to set up a simple barcode reading server in ASP.NET Core with Dynamsoft...

Mobile document scanning apps bring convenience to users by allowing them to scan travel documents, ID cards, passports and other types of documents on the go. This article aims to help C# developers, who do not have the background in computer vision, to build a mobile document scanning app for...

This article aims to help C# developers to build desktop .NET MRZ (Machine Readable Zone) scanner applications with Dynamsoft C++ Label Recognizer SDK. We firstly build a .NET class library for detecting MRZ zone and extracting MRZ text from passport, ID card, and travel documents. Then we demonstrate how to...

Suppose you are a C# developer who wants to use Dynamsoft Document Normalizer to implement a desktop document scanner application. Since Dynamsoft Document Normalizer is a C/C++ library, you may encounter some interoperability issues when using it in your C# project. In this article, we will help you build a...

A few weeks ago, I released a .NET 6 BarcodeQRCodeSDK package implemented with Dynamsoft C/C++ Barcode SDK. This article demonstrates how to build a Windows desktop barcode and QR code scanner using .NET WinForms, OpenCvSharp, and BarcodeQRCodeSDK. This article is Part 4 in a 4-Part Series. Part 1 - How...

.NET MAUI is a cross-platform framework that allows developers to create desktop and mobile applications from a single codebase with C#. It is currently in preview and the production release is slated for Q2 2022. This article goes through the steps to build a .NET MAUI barcode and QR code...

Since .NET 6 Preview 3, it is possible to host Blazor web applications in a WinForms/WPF app using the BlazorWebView control. Behind BlazorWebView is WebView2, which uses Microsoft Edge as the rendering engine to display the web content in native apps. Developers can now adopt a hybrid app approach, utilizing...

Microsoft is pushing .NET technologies to the next level. It is no doubt that .NET framework will be retired in the near future. This article aims to help C# developers to create Windows desktop barcode and QR code reader application using Dynamsoft Barcode Reader SDK. We will firstly create a...

Microsoft .NET 6 SDK empowers C# developers to build cross-platform DotNet applications for Windows, Linux, and macOS from one codebase. This article describes the steps to build a .NET 6 barcode and QR code decoding library based on Dynamsoft C/C++ Barcode SDK, as well as how to pack the library...

In Dynamsoft Barcode Reader SDK, there is a fancy webcam barcode sample called BarcodeReaderDemo that supports reading barcodes from disk files, TWAIN-compatible hardware scanners, and USB webcams. However, one thing you have to know is the functionality of acquiring images from peripheral devices relies on Dynamic .NET TWAIN, which is...

When you release a JavaScript library, such as jQuery, online, you may need to collect some status information for analytics. If you deploy your website on IIS, you can use HTTP Module to capture HTTP requests of HTML, JS and CSS files. My goal is to make a statistic of...

OpenCV is written in C++.  If you install OpenCV library on Windows, you will see OpenCV officially provides wrappers for Python and Java but not for C#. Fortunately, there are many .NET open source projects for wrapping OpenCV C++ APIs, and thus we don’t need to write a wrapper from...

Previously I shared how to use Touchless, which wraps the win32 APIs of DirectShow, to control webcam in C#. In this article, let’s take a further step to see how to use the more complicated DirectShow.NET APIs to capture the video stream and read barcode from preview frames on Windows. Resources for Learning DirectShow.NET DirectShow.NET...

If you have a USB camera, how can you build a simple C# camera application on Windows 10? There are three options:  WIA (Windows Imaging Acquisition), DirectShow and MediaCapture.
