Angular 8 is in the release candidate (RC) phase as of this writing and should be finalized by the end of May 2019. Version 9 should be coming in Q4 of this year.
تغییر loadChildren در نسخه 8
در نسخه 8، استفاده از syntax رشته‌ای برای loadChildren در lazy loading، منسوخ شده‌است:
const routes: Routes = [{
path: 'lazy',
// The following string syntax for loadChildren is deprecated
loadChildren: './lazy/lazy.module#LazyModule'
}]; const routes: Routes = [{
path: 'lazy',
// The new import() syntax
loadChildren: () => import('./lazy/lazy.module').then(m => m.LazyModule)
}]; import مجزای componentهای Material
اگر ازAngular Material استفاده می‌کنید باید Component های مورد استفاده را بطور مجزا import کنید. به عنوان مثال اگر از button استفاده کرده‌اید، باید @angular/material/button را import کنید . البته در اینجا نیز دستور ng update این کار را بطور خودکار انجام می‌دهد.
بهبود CLI با تولید بسته‌های متفاوت ES 5 و ES 6
در نسخه 8، دستور build ارائه شده توسط CLI می‌تواند دو خروجی متفاوت با ES2015 مخصوص مرورگرهای جدید را با حداقل polyfills و ES5 سازگار با مرورگرهای قدیمی را بدهد. در صورتی که بخواهیم build سازگاری با نسخه‌های قدیمی داشته باشیم، می‌توانیم گزینه target در فایل tsconfig.json را به ES5 تغییر دهیم.
برای بروزرسانی پروژه‌های جاری خود می‌توانید از ابزار کمکی ارائه شده توسط تیم angular استفاده کنید.
روش فعالسازی کامپایلر جدید Angular
برای ساخت پروژه‌ای با قابلیت استفاده از ivy compiler می‌توانیم از دستور زیر استفاده کنیم:
ng new angularProjectName --enable-ivy
توجه داشته باشید نیاز است nodejs نسخه 10.9 یا 10.9 به بعد نصب باشد.
پس از ساخت پروژه قسمتی با نام angularCompilerOptions در فایل tsconfig.json مشاهد می‌شودکه نشان دهنده‌ی فعال بودن کامپایلر ivy است:
"angularCompilerOptions": {
"enableIvy": true
} 
In the eighteen years that I’ve been doing Web development, a lot has changed. We started out creating HTML pages to present static information to our users. We then used classic ASP to get database data and incorporate that into our pages. To use both of these technologies, we had to know a lot about HTML, CSS, and JavaScript. Along came .NET and we started rendering everything on the server-side. We forgot a lot about HTML, CSS, and JavaScript as Web Forms wrapped up a lot of that for us. Web Forms’ architecture closely mimicked the way developers created desktop applications. This was great for helping developers move to the Web, but unfortunately hid a lot of the power of the Web, and also tended to be a little slow.
GitHub Issues
The GitHub Issues integration allows you to search and reference your issues from the commit message box in VS, in response to this suggestion ticket. You can reference an issue or a pull request by typing # or clicking on the # button in the lower right side of the commit message text box. If you weren't already authenticated to access related issues, you will now be prompted to sign in to take advantage of this feature.
Line Unstaging
To continue improving our line-staging (aka interactive staging) feature, we've added unstage. You can now use the tool tip option to unstage changes, line by line, as requested here Unstage individual lines and hunks in a file - 4 votes
Arm64
We continue to build native support for Arm64 on Windows 11 for the most popular developer scenarios. We now support the .NET Multi-platform App UI (MAUI) workload on Arm64 Visual Studio.
C++
- Available as a preview feature, you can now view Unreal Engine logs without leaving VS. To see the logs from the Unreal Engine Editor, click View > Other Windows > UE Log. To filter your logs, click on the "Categories" or "Verbosity" dropdowns. Since this is an experimental feature, feedback is greatly appreciated.
- You can now import STM32CubeIDE projects for embedded development within Visual Studio with File > Open > Import STM32CubeIDE project. This generates a CMake project with device flashing and debugging settings for STLink. You must have the STM32CubeIDE installed with the board support package for your device. More details available here.
- You can use the new CMake Debugger to debug your CMake scripts at build time. You can set breakpoints based on filenames, line numbers, and when CMake errors are triggered. Additionally, you can view call stacks of filenames and watch defined variables. Currently, this only works with bundled CMake, and projects targeting WSL or remote machines are not supported yet. We are actively working to add more support to the CMake debugger, and feedback is greatly appreciated.
3 Reasons why Angular 6 is the Future of Enterprise-Scale Web Applications
حجم تقریبا آپدیت از نسخه قبلی (17.8.1) حدود 666G میشه.
Summary of What's New in this Release of Visual Studio 2022 version 17.8.2
- Fixed an issue where, in certain situations, a document window can get stuck showing a loading message.
- In some cases (when a project is located under a solution folder) you may see an error when saving the project. The project would get saved but you would see an error about unable to cast a COM object. This issue is now fixed so the error is no longer displayed.
- RemoteSemanticClassificationService.GetClassificationsAsync: SyntaxTree is not part of the compilation
- When change to another file, VS get stuck on "loading editor components"
- After upgrade to Visual Studio 17.8.0, Interactive REST Tests no longer work
- ASP.NET Core web apps targeting .NET 5.0 and below stopped working after 17.8.0 update
- could not create a .net framework console app
Java is a high-level, cross-platform, object-oriented programming language that allows applications to be written once and run on a multitude of different devices. Java applications are ubiquitous, and the language is consistently ranked as one of the most popular and dominant in the world. Christopher Rose’s Java Succinctly Part 1 describes the foundations of Java–from printing a line of text to the console, to inheritance hierarchies in object-oriented programming. The e-book covers practical aspects of programming, such as debugging and using an IDE, as well as the core mechanics of the language.

This lets you do things that you can’t do in WebAPI’s default binder, specifically:
- ModelBinds everything, including the body. Assumes the body is FormUrl encoded
- This means you can do MVC scenarios where a complex type is bound with one field from the query string and one field from the form data in the body.
- Allows multiple parameters to be bound from the body.
C# 9.0 is taking shape, and I’d like to share our thinking on some of the major features we’re adding to this next version of the language.
