What is .NET?

In this article, we will learn about .NET. We will also learn about .NET features and the types of applications we can build using it. Finally, we will see why you should learn .NET, available .NET jobs, and .NET developer salaries. 
 
.NET is a free, open-source, and cross-platform for building modern, scalable, and high-performance desktop, web, cloud, and mobile applications. The current version of .NET is .NET 5.0, which is the successor of .NET Core 3.1 and .NET Framework 4.6. Prior to .NET 5.0, .NET had two versions, .NET Framework, and .NET Core, but in this version, both have merged and now there is only version.
 
.NET is a single unified platform to build desktop, web, cloud, mobile, gaming, IoT, and AI apps. The .NET ecosystem has a single common library, runtime, language compilers, and tools.
 
What is .NET 
 
The following is a list of .NET components: 
  • Application frameworks and libraries
  • .NET Standard
  • Runtime Components
  • Language Compilers
  • Languages – C#, F#, and Visual Basic
  • Tools - Visual Studio, Visual Studio for Mac, Visual Studio Code, and Command Line Interface (CLI) are tools used to build, test, and deploy .NET applications. 
.NET application frameworks and libraries
 
.NET can be used to develop the following types of applications:
 
Desktop applications
 
.NET provides four major technologies to build desktop applications, WPF, Windows Forms, UWP, and Xamarin.
 
Web applications
 
ASP.NET is a set of libraries and tools to build web applications including front-end websites, APIs, and Microservices.
 
Blazor is the newest addition to .NET. Blazor is a single page web app framework built on .NET that runs in the browser via WebAssembly. A Blazor application can be deployed as a set of static files without the need for any .NET support on the server.
 
 
Mobile apps
 
Xamarin is a tool that is used to develop native mobile apps using C#.
 
Cloud-native applications
 
Cloud has become the prime destination of software applications. Cloud native apps are designed to build, test, and deploy in the cloud. Cloud-native apps are modern, high performance, automated, and highly scalable. The key features of cloud-native apps are modern design, the use of microservices and containers, backing services, and automation.
 
Games
 
.NET works well with Xamarin and Unity to develop game apps for mobile and gaming consoles. Unity is one of the most popular gaming development tools and supports C# and .NET development and works well with Visual Studio.
 
Internet of Things
 
.NET can be used to build IoT systems. It's multi-platform and supports hundreds of sensors, displays, and input devices that can use GPIO, SPI, I2C, PWM, SerialPort, and more. Sensors include popular DHT Temperature and Humidity, accelerometers, lights, gas sensors as well as more complex hats like GrovePi, Adafruit Seesaw, Sense HAT, RFID modules like PN532, and extended like FT4222. For a full list of bindings, see Device bindings.

Why .NET?
 
Today, we build software to target various devices and platforms. Devices include desktops, laptops, tablets, and smartphones. Platforms are Windows, Linux, and Mac. Besides these common devices and platforms, there are more devices and platforms out there. Internet of Things (IoT), cloud platforms, gaming devices, TVs, refrigerators, and cars are other popular devices that run on software.
 
.net application types 
 
.NET is a software development platform for building software applications for all these devices. That means, once you learn .NET, you can start building applications for desktops, web, cloud, mobile, gaming, IoT, and more devices.
 
Here are the key characteristics of .NET: 
  1. .NET is open source and available on Github for free to download and open to community contributions. While the direction of .NET development is lead by a dedicated team of experts at Microsoft, a majority of the development is decided by a large open-source community. 
  2. .NET is cross-platform and supports all Windows, Linux, and Mac OS. A .NET application can be developed using a single code base and run on multiple platforms.
  3. .NET is a modern software development platform and supports a majority of modern software development needs including native mobile, cloud, web, and services. 
  4. .NET supports multiple languages including C#, F#, and Visual Basic. 
  5. .NET is cloud-native and allows developers to build cloud-based web applications, services, and APIs.
  6. .NET offers some of the best software IDE and tools including Visual Studio and Visual Studio Code.
  7. .NET is fast and friendly and plays well with other languages and platforms.
.NET current version and future releases
 
.NET is mature and yet still evolving. The first version of the .NET framework was released on Feb 14, 2002. The current version of .NET is .NET 5.0 that was released in November 2020.
 
.NET Release Schedule 
 
.NET team has announced the released dates of upcoming versions and is expecting to release one major version every year in November. As you can see from the above release schedule, .NET 6.0, 7.0. and 8.0 will be released in Nov 2021, 2022, and 2023 respectively.
  
C# 9.0
 
We can’t finish talking about .NET without talking about its primary programming language C#. C# is one of the most popular programming languages in the world. C# is also the most versatile programming language among them all. 
  1. C# is simple, clean, and modern.
  2. C# is safe, productive, and fast.
  3. C# is open source.
  4. C# is a language for all kinds of software applications.
  5. C# is a language for emerging technologies.
  6. C# is evolving. 
C# 8.0 is the latest public version of C# language while C# 9.0 is knocking the door and expected to be released in Nov. 2020 with the release of .NET 5.0. C# 8 has the following new features: 
  • Default interface methods
