What is .NET Core

When it comes to developing and writing enterprise grade technologies, no one does it as gracefully as Microsoft. .NET Core is one such general-purpose framework used across the globe to build software applications for Windows, Linux, and MacOS. Compared to other software frameworks, .NET Core is much more versatile and meticulous; used to build each and every kind of software including Web applications, Mobile apps, Desktop applications, Cloud services, Microservices, APIs, Games, and IoT applications.

Most developers would have felt that .NET Core is not limited to a single programming language and supports C#, VB.NET, F#, XAML, and TypeScript, which is unlike any other framework. These are open source programming languages,managed by independent communities.

Why .NET Core?

Without a doubt, it presents the most advanced, mature, and extensive class libraries, common APIs, multi-language support, and tools. What’s better? The Visual Studio 2019 and Visual Studio Core are currently the most advanced and modern developer IDEs. This makes .NET Core one of the most productive platforms in .NET Core development for developers.

Chronicles of .NET Core

As we noted earlier, .NET Core was first developed by Microsoft; one of the brightest feathers on their cap. As of now it is managed under the .NET Foundation which is a non-profit open source organization. .The framework has been written in C# and C++ and is licensed under MIT license.

The prime version of .NET Core, 1.0, was first released back in 2016 and without a doubt had very limited functionality. The next version came in August of 2017, .NET Core 2.0. And the story continues after that.

The hallmarks of .NET Core

Even though the first version had limited functionalities, the latest version of .NET Core has extensive capabilities with modern and powerful features. Some of the amusing characteristics of .NET Core include open source, cross-platform, modern, flexible, lightweight, fast, friendly, shareable, and built for future software development.

Being Free and Open Source

The entire .NET Core platform is free and open source, giving expert developers a vast playground where they can develop futuristic enterprise-grade applications. You can easily .NET Core source code project is available on Github. A huge number of active developers participate in .NET Core development with a drive to improve the existing features, adding new features, and fixing bugs and issues.

Currently more than 60,000 developers and 3,700 companies are contributing to the .NET ecosystem.

.NET Core is Modern

Shifting away from older frameworks and functionalities, the .NET Core framework is built to solve today’s modern needs, some of them include being mobile friendly, building it once and running it everywhere on all platforms, scalable, and high performance.

It is Cross-platform

The framework supports and runs on Windows, macOS, and Linux operating systems.It is also amazingly consistent across architecture including x64, x86, and ARM. You can import and use the same assemblies and libraries on multiple platforms.

.NET Core supports modern language constructs using C# version 8, like object-oriented and modular programming, generics, collections, lambdas, Language Integrated Query (LINQ), and asynchronous programming.


When compared to the .NET Framework and .NET Core 2.2 and previous versions, .NET Core 3.0, the latest version is superiorly fast. Also, it is faster than compared to current server-side frameworks like Java Servlet and Node.js.

Lightweight and Friendly

You will find that the framework is extremely lightweight; it can be included in your app or installed side-by-side user, machine-wide, or on a server. You can deploy .NET Core in Docker containers.

Additionally, the .NET Core framework is aptly compatible with .NET Framework, Xamarin, and Mono, via .NET Standard. You will also get support while working with other popular Web frameworks and libraries like React, Angular, and JavaScript.

Types of apps that can be built using .NET Core

Since .NET Core is a general-purpose software development framework, it easily allows developers to build a plethora of software including Web, Desktop, Mobile, Cloud, Gaming, IoT etc.

The applications built with .NET Core are supported on Windows, Linux, and macOS.

Web Applications:- The core component of .NET Core diaspora is ASP.NET Core, a framework good for building web pages. ASP.NET Core comes from the lineage of MVC architecture and provides common libraries to build the Web.

Mobile applications:- With Xamarin offering a set of tools and libraries for building cross-platform mobile apps using C#, developers can build native apps for iOS, Android, Windows, and macOS on a shared .NET codebase with seamless functionality.

Desktop Applications:- You get a myriad of tools and frameworks with .NET Core to build desktop applications. If you want to start building desktop applications, Windows Forms, WPF, UWP, and Xamarin are four major pillars for you.

Cloud Apps:- With cloud gaining traction across the IT sector, the demand for cloud apps has also surged. Azure has support for all kinds of cloud apps. You can deploy .NET Core and C# based apps on Azure with Visual Studio 2019.

Internet of Things:- The most popular domain across information technology today is IoT. You can get .NET Core support for IoT development via UWP framework for IoT devices running Windows 10 IoT Core.

Games:- You can use C# and UWP are used to build games for mobile, desktop, console, TV, VR, AR and the Web. WIth support from Unity, one can make astounding games.

Latest features and tweaks in .NET Core 3.0
