.NET in 100 Seconds

Key Takeaways

The.net, a free and open- source platform for building high performance software in virtually every domain. It can tackle web apps, mobile apps, enterprise software, games, and more. Powered primarily by the C programming language. It was developed by Microsoft in the early 2000s as a Windows-centric framework, then rebooted in 2016 as .NET Core. And finally, in 2020, they dropped the core and unified the platform into modern.NET NET with yearly releases that also target Linux, Mac OS, and the cloud. At a high level, .NET is built around a managed runtime called the common language runtime, which handles memory management, garbage collection, and security, so you don't have to. This allows developers to write code in highlevel languages like object-oriented C or its cooler functional brother F or even the mentally ill cousin Visual Basic. No matter which language you choose, they all get compiled into an intermediate format called common intermediate language. then just in time or ahead of time compiled into native machine code by the common language runtime. This design lets multiple languages share the same runtime and libraries while still delivering near native performance across platforms. But what really makes .NET special is its integrated ecosystem like ASP.NET for regular web apps, Blazer for web assembly powered apps, Entity Framework Core for dead simple database access, Maui for cross-platform mobile apps, and Poly for fall tolerance just to name a few. And you'll find packages for virtually every use case in the Nougat package manager. On top of that, many thirdparty frameworks embed.NET to give developers the experience they crave, like Unity for game developers, Quant Connect for Algo Traders, and AutoCAD for real engineers who build real things in the real world. To get started, install.NET, then open up VS Code, and make sure you have the C DevKit extension enabled. Now, hit control P and find the new project command. There are all sorts of templates to start from, but let's keep it simple with the console app to build a CLI tool. And now we can open up this C file and start writing some code. It's a hugely popular, strongly typed language that gives us excellent IntelliSense out of the box. Today, we're building an app called Only Horse Fans. And unfortunately, we need to verify that the user is 18 years old to comply with recent draconian legislation from our globalist overlords. To achieve that, we'll first have the user enter their age into the console, which we can do with the built-in console class. Once we have the user's age in the standard input, we can then parse the value into an integer. And then finally, we'll set up a turnary operator here to grant access if the age is over 18 or deny access otherwise. And now let's open up the terminal and run it. Notice how we also get beautiful autocompleted documentation in the entire CLI. Use then run command to compile and execute the code. This has been net in 100 seconds.
