Microsoft has just released .NET 6.0 with lifetime support and Visual Studio 2022, a versatile Windows IDE. In this article, we will learn about this new release of Microsoft. In this article, I will Share Key Active Visual Studio Enterprise 2022.

.Net 6.0 and Visual Studio 2022 what’s new

This release is a big event for Microsoft’s development platform as .NET 6.0 is the first LTS release since .NET Core 3.1 in December 2019. LTS releases are expected to launches every two years, with short-term releases in between. The current .NET 5.0 will end support in mid-2022.

Development using .NET 6 is not supported in Visual Studio 2019. Visual Studio developers who want to use .NET 6 must immediately upgrade to Visual Studio 2022. Cross-platform Visual Studio Code users will be more comfortable , just download the .NET 6.0 SDK.

The relationship between .NET and these two types of Visual Studio (including Mac versions) has been controversial recently since Microsoft plans to remove the Hot Reload feature from the SDK to make Visual Studio more attractive. more lead. This decision immediately received a wave of outcry, especially after the .NET Foundation was revealed to be legally binding with Microsoft and not truly independent, despite its claims.

In an article marking today’s release, Microsoft boasted of a “significant increase in performance”, as a result of which it reduced the “cost of hosting cloud services at Microsoft”.

There’s a lot more to it than you’d expect, especially for those of you who’ve dropped .NET 5.0. The C# language is now at version 10 including using global directives, value type constructs, string interpolation and many more new features, while F# is at version 6.0, including task support and more.

The aforementioned Hot Reload feature allows us to edit the source code while the application is running, and display the results without having to rebuild the project. Blazor WebAssembly now features pre-compilation: this technology allows C# to be used to code browser applications that run on the client as well as on the server. HTTP/3 support has been added to ASP.NET Core. Apple Silicon is also supported. Single file applications, described as “a single binary with exactly one file on disk and without the need to extract any core runtime to a temporary directory”, are now supported on Windows and macOS as well as Linux.

Visual Studio 2022 is the first 64-bit release of the IDE itself – although it has been able to compile 64-bit applications for years – and includes “AI-powered code autocompletion” called IntelliCode, although there’s no news on GitHub yet. Copilot advanced in Visual Studio, but I think it will likely appear someday in the future. Copilot for Visual Studio Code remains in invite-only preview. The Find in Files feature is claimed to be “3 times faster”. The team says that the IDE is “lighter” than before, presumably learning from its VS Code cousin.

Other new features in Key Active Visual Studio Enterprise 2022 include support for projects in multiple Git repositories, to an improved user interface with a new font for code called Cascadia and refreshed icons .

Visual Studio has three versions. Community is free and supported for individuals or for up to five users in “non-business organizations,” defined as organizations with less than 250 PCs or less than one million US dollars in revenue. These businesses are not licensed to use the Community edition to develop and test applications except in limited circumstances, such as for open source software. Enterprises is a paid and unlimited version. The Enterprise edition adds features like IntelliTrace debugging (which records and tracks code execution history), Code Coverage, and other performance and testing tools.

While all of that looks good, there are some disappointments for .NET developers. One is that Microsoft recently confirmed that .NET 6 will not appear on UWP (Universal Windows Platform) applications. Windows desktop developers are being moved towards WinUI 3 and the Windows App SDK or can continue to develop with the legacy Windows Forms and Windows Presentation Foundation, although if the latter path is chosen, they will not get it. the full Windows 11 interface that Microsoft calls Fluent Design. Another issue is that the cross-platform MAUI (Multi-Platform App UI), based on Xamarin technology, is not ready yet and is still in preview, scheduled for release next year. MAUI allows desktop and mobile apps to be built for iOS, Android, macOS, and Windows, from a single code base.

Key Active Visual Studio 2022 Enterprise

Advantage: Load projects faster, AI suggests better code, suggests a whole line of code, not 1 2 words like 2019

Defect: Blazor’s editor is not very good, the format is not standard, some extensions still do not support the 2022 version
The rest are generally better than the previous versions

Red Hat Enterprise Linux (RHEL) and Ubuntu are two of the most popular Linux distributions in the open source world. Of course, they are distinct and commercially successful, but what about other aspects? Who should use Ubuntu? And, should you consider using Red Hat Enterprise Linux for anything?

Let’s explore the differences of the two distributions above in this article.

History of Red Hat and Ubuntu

Red Hat, now a subsidiary of IBM – was founded in 1993, headquartered in Raleigh, North Carolina, USA. A few years later, Red Hat Linux was born on May 13, 1995.

Early versions of Red Hat’s Linux distributions were called Red Hat Commercial Linux or Red Hat Linux.

Red Hat Enterprise Linux (RHEL) is a Linux distribution created, maintained, and supported by Red Hat Inc., which was first released on February 22, 2000. This resulted in “Red Hat Linux” discontinued in 2004.

Ubuntu (based on Debian) was introduced by a UK-based company, Canonical Ltd., founded by Mark Shuttleworth, a South African businessman. It was originally released on October 20, 2004.

1. Target audience

Red Hat and Canonical focus on the management and licensing of open source software products for businesses.

However, Red Hat Enterprise Linux is just an enterprise-focused product, while Ubuntu is geared towards business and personal desktop users.

It is important to note that Fedora Linux serves as the upstream and serve non-commercial users. So if you want the Red Hat experience on your desktop, Fedora Linux will give you the closest thing.

2. Paid or free

The biggest difference between the two Linux distributions is its access rights and subscription model.

Although Red Hat is the largest open source company, RHEL requires you to register for the most part, whereas Ubuntu has no such requirement.

Since you need a subscription (you can’t download packages from the RHEL repository if you don’t), inviting people to “try out” RHEL can be a barrier for new users.

So in January 2021, Red Hat announced that individuals could sign up for free to use RHEL on their computers. It is limited to 16 servers at a given time.

While RHEL is free, it won’t be completely free if you have more servers in your business.

Tip, you can check the registry status on your RHEL system with the following command:

sudo subscription-manager status

On the other hand, Canonical (Ubuntu) has a relatively different working model. You don’t even need an account to download or use Ubuntu.

Canonical offers Ubuntu for free, and you only need to sign up (called Ubuntu Advantage) if you need commercial support.

If you have an Ubuntu Advantage subscription, use the following command to check the support status of your Ubuntu system:

ubuntu-security-status

For older versions of Ubuntu, the following command should work for you:

ubuntu-support-status

Overall, if you need expert help and want to access enterprise features, you’ll have to pay for Ubuntu and RHEL.

However, when it comes to personal use or standalone use of Ubuntu/RHEL, Ubuntu is completely free and RHEL limits usage to 16 servers.

3. Support Lifecycle

Using a Linux distribution is only interesting when there is a well-defined upgrade lifecycle and a known “shelf life”.

Here is a chart comparing RHEL 8 with Ubuntu LTS 22.04:

When it comes to RHEL 8, Red Hat has 3 phases to support:

• Full support: for 5 years from release
• Maintenance Support: for 5 years after “Full Support” ends
• Extended life period: for 2 years after “Maintenance Support” ends

In the ‘Extended Life Phase’ you can select ‘Extended Lifecycle Support’ (ELS) to receive Security and Bug fixes.

Canonical releases a new LTS version every April in an even number (or every two years).

For example: Ubuntu 18.04 released in April 2018, Ubuntu 20.04 released in April 2020 and Ubuntu 22.04 released in April 2022, etc.

Ubuntu LTS releases are “enterprise grade”. You can see the version Long term support for more.

Starting from the day a new version of Ubuntu LTS is released, Ubuntu has the following two phases of support:

• Hardware updates and maintenance: for 5 years from the date of release
• Extended security maintenance: for 5 years after the initial support period ends, Ubuntu Advantage subscription is required

For a business, both distros are good at getting maintenance updates for a long time. But

4. Software repositories and package managers

As with any Linux distribution, both RHEL and Ubuntu provide and maintain first-party software repositories for their Linux distributions.

If you’re curious, RHEL has the following first-party repositories:

• BaseOS
• AppStream
• EPEL (Extra Packages for Enterprise Linux)
• PowerTools

To fetch and install packages from these software repositories on your RHEL system, you need to use the dnf or rpm package manager to install, update, and remove packages.

Tip: when Fedora switches to using dnf by default, you should learn to use the DNF package manager instead of yum.

For comparison, Canonical offers the following software repositories for Ubuntu:

• Main
• Universe
• Restricted
• Multiverse
• (extra) Canonical Partners

Since Ubuntu is derived from Debian, it uses apt and dpkg package managers.

Different Linux distributions using different packaging formats with different versions of libraries (sometimes, even the same library can have a different name on Arch than on Ubuntu) has created a divide Piece.

To get around this and package software in such a way that the same binary package can be installed on any Linux distribution (due to the same architecture), common packaging formats have been adopted. create.

Red Hat supports the Flatpak package with RHEL, as it was created by Liberationesktop.org (an effort focused on interoperability and sharing technology for open source graphics and computer systems).

And, Canonical supports snap package with Ubuntu releases (including LTS).

5. Other minor differences

There are a few small but significant differences between RHEL and Ubuntu LTS that I would like to mention.

Calendar release

As mentioned earlier, Canonical releases a new LTS version of Ubuntu every April, with even numbers.

RHEL doesn’t have a strict release schedule like Ubuntu.

Security

Of course, we know that Linux is generally safe, as it gets security patches faster. Maybe it’s one of those why Linux is better than Windows.

And, we also know that nothing is ever 100% secure.

In this case, the team behind RHEL and Ubuntu ensures that the Linux distributions are secure enough to protect all businesses.

The main difference between RHEL and Ubuntu (for enterprise customers) is the security system used.

RHEL (and Fedora) use SELinux as a security system. Ubuntu on the other hand uses AppArmor. The difference between them is beyond the scope of this article so I will not explain it here.

Container Virtualization

There has been a great advance towards software containerization on Linux as it provides easy migration (from a failing node to another working node), sandboxing, and other benefits.

And if you are a business, chances are high that you will take advantage of containers.

Both Canonical and Red Hat have container management systems to make things more convenient for you.

Red Hat has OpenShift (open source) in its product portfolio and is best used on the RHEL system (but is also available for use on other distributions). Red Hat also developed podman, an open source tool for working with containers on Linux, intended as an alternative to docker. This is achieved because it is OCI compliant.

Canonical has created MicroK8s (open source), called ‘Canonical Kubernetes’, for automatic deployment, scaling and management of applications contained in Ubuntu systems.

Should businesses choose Red Hat Enterprise Linux or Ubuntu?

As is clear from the above, both RHEL and Ubuntu are capable enough to handle personal and business use cases.

It depends on your needs, whether you want to subscribe (or if you find the subscription model expensive).

Ubuntu is a popular name for desktop and server usage, while RHEL focuses solely on enterprise services. So Ubuntu can be an attractive option for small/medium businesses or individuals who are already comfortable and confident using Ubuntu on their systems.

If you don’t depend on Ubuntu, you can try anything that suits your requirements or the technology that’s right for your business/product.
