.NET in 100 Seconds

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. Thanks for watching and I will

see you in the next
