Unleashing the Power: Discovering the Top C# Libraries for Productivity

C# (pronounced “see sharp” or “C Sharp”) is one of the most popular programming languages, like Java. It’s object-oriented and allows you to build reusable components for a wide variety of application, ranging from desktop software to web applications and even mobile apps. One of the factors that contribute to its popularity and efficiency is the availability of numerous libraries that extend the language's capabilities. In this article, we will explore some of the most useful C# libraries that can significantly enhance your development experience and productivity.

The useful C# libraries -

1. Best libraries for image processing

C# libraries can be used to create versatile and highly useful for image processing. These are used to edit, change, distort, and process images. It’s so powerful for image processing. With these image processors, you can change and manipulate colors, image orientations, add a filter and blend effects, change image size, and much more. C# provides built-in image processors such as -

  • ImageProcessor - It's collection of lightweight image processing libraries built using C#. ImageProcessor gives the user the ability to edit and manipulate images quickly and easily on both desktop and mobile applications. The project is open source and completely free to download, install, and use.
  • CSharp Image Library - CSharp Image Library is an image processing library built entirely in C#. It supports jpg, png, bmp, TGA, and gif image formats. It’s speedy, lightweight, and has some interesting color-related and color-splitting features.
  • Emgu CV - It's an open source library that uses the OpenCV library as a basis for its image processing features. It works by allowing OpenCV core functions and functionalities to be called by any .NET language (including C#). It’s written in C# and is highly portable - it’s supported on Windows, Mac, and Linux operating systems.
  • RasterEdge - It's a powerful library written in C# for image manipulation, processing, and modifying. With it, you can isolate regions of an image to process, you can flip or rotate an image, mirror an image, edit and change colors, play with blending and sharpness effects, and much more. The library gives you a lot of options for ways in which you can process your images.

2. Physical Measure library

Physical Measure is a C# library for handling physical quantities by specifying value and unit. Scaling of units and conversions between multiple unit systems. It can be used to represent and handle physical measures and calculations of physical properties. PhysCalc is a calculator using Physical Measure to evaluate physical expressions.

3. System.Security

It contains classes that represent the .NET Framework security system and permissions. Child namespaces provide types that control access to and audit securable objects, allow authentication, provide cryptographic services, control access to operations and resources based on policy, and support rights management of application-created content.

4. System.Transactions

It contains types that support transactions with multiple, distributed participants, multiple phase notifications, and durable enlistments. A child namespace contains types that describe the configuration options used by the System.Transactions types.

5. Log4Net

Log4Net is a port of the well-known logging framework for Java log4J. It allows a much more granular approach to program debugging. With log4net it is possible to enable logging at runtime without modifying the original application binary and without incurring a high-performance cost. Multiple “levels” of logging can be set within your program as well, and so you can determine quickly where “fatal” errors occur, and where “warnings” occur that can be ignored in the safe running of your application.

6. System.Windows

System.Windows contains used in Windows Presentation Foundation (WPF) applications, including animation clients, user interface controls, data binding, and type conversion. System.Windows.Forms and its child namespaces are used for developing Windows Forms applications.

7. System.Xml

System.Xml namespaces contain for processing XML. Child namespaces support serialization of XML documents or streams, XSD schemas, XQuery 1.0 and XPath 2.0, and LINQ to XML, which is an in-memory XML programming interface that enables easy modification of XML documents.

8. FileHelpers library

The FileHelpers library was created to stop developers from continuing to parse CSV. If you are doing any kind of importing and exporting within your application using the CSV format to get data in or out, look no further. You can strong type your flat file simply by coding up a class that maps a data type to each record. This way data consistency, and import/export reliability can be tightened up on quite a bit.  Writing out to a new file is also pretty easy once you’ve created your base classes defining the structure. Great little library for your toolkit.

9. Pdfium.NET SDK

It's a class library based on the PDFium project for viewing, text extracting, navigating and editing PDF files in your .NET projects. With the PDF Viewer control, you can display PDF files directly in your WinForms and WPF application without the need to install an external PDF viewer.

10. Elmah

Elmah stands for error logging module and handlers. It is completely pluggable in the system for error handling within your .NET app. It catches bot thrown and unhandled exceptions across the scope of your app log them and allow you to browse the full stack trace, all without exposing the error to the users of your application. That’s useful for a number of reasons. Firstly you aren’t getting the performance hit of using debug=true within your application, means, you can still get to the bottom of little blips as and if they happen. Elmah works as an HTTP module, so it takes little or no effort to deploy on any project. Only have to configure a few bits, and it goes.

11. Enterprise DT FTP library

Enterprise DT is a great little FTP library, that performs all the needful without you getting your hands too dirty. It works with both web and offline applications, and again is a port of a Java library. It’s really easy to use and saves you from having to write your own FTP operations.

12. Wix#
