AI Creator's Path News: C# 10 evolves in .NET 5 Preview 14! Runtime improvements too! Must-see for developers! #NET10 #Csharp14 #dotnet
Video explanation
Hello! Welcome to the world of AI and technology!
Hello everyone! I'm John, an IT journalist. Smartphone apps and websites make our lives easier. Have you ever wondered how they are made? In fact, behind the scenes, powerful development tools such as ".NET" are at work.
Today, I would like to introduce the latest information on .NET, especially the new version called ".NET 10 Preview 5", in an easy-to-understand and fun way, even for those who do not have specialized knowledge. Don't worry if you are wondering "What is a preview?" or "Is C# a code?" Let's take a look together!
What is ".NET" anyway? What is the latest version, ".NET 10 Preview 5"?
First, let me briefly explain what ".NET" is. .NET is a standard provided by Microsoft.A big toolbox for developing softwareIt's like this. This toolbox contains programming languages (languages for giving instructions to a computer) and many useful tools to help with development. A whole lot of things are made using .NET, including websites, smartphone apps, games, and company systems.
The ".NET 10 Preview 5" announced this time is the latest version of ".NET 2024", which is scheduled to be officially released in November 11.The fifth installment of the "trial version (preview version)"Before releasing the official version, it is released to developers as "This is what it will look like, everyone, give it a try!" In this way, we make small improvements and end up with a better product.
There are many improvements in this Preview 5, but we'd like to pick out a few points that we think are particularly noteworthy!
C# 14 has evolved! It's easier for programmers
"C# (C Sharp)" is one of the most popular programming languages used in .NET. This C# has also been upgraded to "C# 14", with new features added.
Among them, the most notable is "User-defined compound assignment operators" ...That's a bit of a difficult word right off the bat (laughs).
Simply put, the idea is that programmers will be able to create their own convenient shortcut commands. For example, let's say you often do something in your program like "add B to A and put the result in A." Writing this every time is a bit of a hassle, isn't it? So, with this new feature, you can decide your own rules so that just writing "A += B" will have the same meaning (this is a feature that was already available, but the idea is that it can now be customized even more freely).
If we use a cooking analogy, it would be like registering your "usual seasoning" as a step and then reproducing it with the press of a button. For programmers, this is a welcome improvement that makes the code neater and makes development easier.
Program execution becomes smarter and faster! Evolution of "runtime"
"Runtime" refers to the environment in which the programs we write actually run on a computer. This runtime has also become smarter in various ways in this Preview 5.
- Improved escape analysis :
This is a bit technical, but think of it as an improved mechanism for "intelligently checking to prevent programs from running in an unnecessary manner." For example, there is data (called variables) that a program uses temporarily while working, and it will check more thoroughly whether it is being used only when it really needs to, and whether it is taking up memory (computer working space) unnecessarily. This makes the program run more efficiently, resulting in faster speeds and reduced memory consumption. - JIT Compiler Improvements :
"JIT compiler" is an abbreviation for "Just-In-Time Compiler," and is like a smart translator that translates human-written program code into language that a computer can understand (machine code) at the moment the program is executed. The "inlining policy" of this translator has been improved. "Inlining" is a technique that speeds up processing by embedding frequently used short processes directly in their place, rather than calling them every time. With this improvement, inlining can be performed more effectively, leading to improved program performance.
While we users don't see these improvements directly, they're the important "unsung heroes" that make apps and websites run smoother and more responsively.
And much more! Featured updates
Preview 5 also includes improvements in a variety of other areas. I'll briefly introduce some of them here.
- The evolution of F# 10 :
F# is one of the programming languages that can be used with .NET. In the latest version upgrade (F# 10), a feature called "scoped warning control" was introduced. This is a function that gives advice (warnings) to programmers such as "Maybe it would be better to write this part a little differently," and now the scope of the warnings can be controlled more finely. - Improving security for ASP.NET Core :
ASP.NET Core is a framework (a framework or set of tools to make development easier) for creating websites and web services. With this update, you can now set more detailed access permissions for the request queue (a place that temporarily stores requests to access the web server) using a mechanism called HTTP.sys. This allows you to make application security more flexible and stronger. - Improved "Page not found" display in Blazor :
Blazor is a technology that enriches the appearance and behavior of websites. When you are browsing a website and try to access a page that does not exist, you may see the message "Page Not Found." Now developers can customize this display more easily. - .NET MAUI makes development easier :
.NET MAUI is a convenient framework that allows you to develop smartphone apps (iPhone, Android, etc.) and PC desktop apps all in one code. With this improvement, the way to write XML namespaces (a mechanism to prevent program component names from overlapping) has been simplified, making development a little clearer. - Improved usability of WPF (Windows Presentation Foundation) :
WPF is a technology for creating desktop applications that run on Windows computers. This update makes it possible to shorten the writing process for defining screen layouts in XAML (a language for designing the appearance of apps), and also supports "XAML hot reload" (a function that reflects changes to the code on the screen immediately after they are made). This makes it much easier to adjust the appearance. Performance is also said to have been improved.
Summary: Keep an eye on the ever-evolving world of .NET!
This time, I tried to explain the main new features and improvements of ".NET 10 Preview 5" as clearly as possible. There may have been a lot of technical content, but I hope that I was able to convey at least a little of how .NET is evolving day by day so that developers can create more comfortable and higher performance applications.
It includes a wide range of updates, from improvements to the programming language, to performance improvements to the execution environment, and improvements to the usability of each framework. I'm even more excited for the official release scheduled for November!
A comment from the author
At first glance, these technological advances may not seem relevant to us average users. But they're actually an important step toward making the apps and services we use every day faster, safer, and more convenient. The next time you use a new app, it might be interesting to take a moment to think about the efforts of the engineers working behind the scenes.
