.NET has been sitting at the heart of the IT industry for over 20 years since its launch in 2002. During this timeline, the Microsoft framework has gained an enormous following among software developers and businesses alike to build various apps. Although there is no official record, it is fair to claim that millions of web, mobile, and desktop applications run on .NET across nearly every operating system. The world of .NET keeps evolving, giving developers a fresh batch of handy .NET development tools that streamlines day-to-day tasks, enhances productivity, and helps them code fast and reliable apps.

According to a 2024 Statista report, nearly 25.2% of software developers use the .NET (5+) Framework to develop top-notch custom apps. Even though these are big numbers, there is still plenty of room for you to carve out a distinct name for yourself in the custom .NET development space. However, to do so, you need to get familiar with the best development tools for .NET that can enhance the process of app development and be deployed in various industries. So, let’s jump into the blog to know the right tools.

Introduction to .NET Framework: Meaning & Benefits

Launched by Microsoft on February 13, 2002, with v1.0, the .NET Framework is a proprietary software development framework. It’s part of a wider .NET family with a full developer ecosystem that bundles tools, languages, and libraries so people can build all kinds of applications. It comes in several versions, and each one lets the same code run in a different environment.

The .NET Framework was the first edition, often simply referred to as “ .NET Framework.” It acts like a virtual machine that gives developers a shared platform where programs written in C#, F#, Visual Basic, and other languages can work together without issues. With this framework, programmers can design desktop forms, command line tools, mobile components, and web services that can run smoothly inside the Microsoft ecosystem. Simply put, its main aim is to craft applications that will run smoothly on Windows.

Furthermore, .NET is actually a cross-platform framework. It powers websites, services, and console apps on Windows, Linux, and macOS. It was previously known as. NET Core/.NET. Since its inception, .NET has been adopted by organizations ranging from small businesses to multi-national corporations. With this robust cross-platform application development framework at their disposal, developers can develop apps that work on multiple platforms.

Topics are better understood if you approach them in a step-by-step manner. So, before introducing you to the top development tools for .NET, let’s understand its benefits that make this framework so popular:

1. Supports Multiple Programming Languages: For custom app development projects, you can choose any preferred programming language (C#, F#, or VB.NET).

2. Fast Performance: Apps built on the framework start quickly, respond instantly, and benefit from just-in-time compilation that performs well even under high load.

3. Cross-Platform Compatibility: The .NET framework is compatible with any operating system, whether it’s Android (APK), iOS (IPA), or Windows (EXE).

4. Ergonomic & User-Friendly Design: The built-in UI controls and a solid MVC architecture of this open-source platform provide a clean, ergonomic workspace, letting experienced developers focus on features
