The official line is that the support for Microsoft .NET Core 2.1 will no longer be available from 21st August 2021. From that date, .NET Core 2.1 will stop receiving updates, security patches, or bug fixes. Those who are planning to initiate .NET projects should look for service providers that are using newer versions of this system.
Originally, .NET Core shifted from the conventional .NET framework in an attempt to come up with an open-source, cross-platform framework that could support .NET in the future. .NET Core appeared in three different variants and ended with .NET Core 3.1. Microsoft released it in December 2019.
According to experts, the official support for .NET Core 2.1 from the house of Microsoft will no longer be available from 21st August 2021. After that date, .NET Core 2.1 will stop receiving bug fixes, updates, and security patches from Microsoft. So, if you have any .NET project for your .NET development company to work on, make sure they’re using a newer version of the system.
In 2020, however, .NET 5 popped up. As a result, the framework currently incorporates every feature and improvement created in .NET Core and even in the standard .NET roadmap. Now, the real question is – what does it have to do with business organizations using .NET Core 2.1?
Fortunately, the name of the creator of .NET and .NET Core is Microsoft – a name you can trust. It’s a tech giant that never leaves its users hanging, whether it’s a .NET development company, a solo developer, or an end-user. Jamshed Damkewla is the Principal Engineering Manager at .NET Microsoft, who recently wrote in a blog post that everyone should consider shifting from .NET Core 2.1 to .NET Core 3.1 before the deadline.
It’s also worth mentioning here that simply upgrading to .NET Core 3.1 won’t be enough. You must transport every application running on the older variant to the newer version, and you have to do it before August 21st, 2021.
Other recommendations
As already mentioned earlier, .NET 5 is a product of 2020, and there’s a possibility that .NET Core 6 will appear sometime in November 2021. That’s why every trending .NET development company should replace older versions of the framework with the latest version.
Transitioning from .NET Core to .NET 5 is going to be a relatively straightforward process because the necessary tools are already available in the current version of Visual Studio. Nobody can say that it will remain as easy to upgrade in the future as it is now.
Do you think it’s possible to support applications built using .NET 2.1 with the tools and frameworks of today? Doesn’t it sound absurd to you? If it does, then isn’t it sensible to start searching for ways to avoid those issues for your business as soon as possible?
You’re probably second-guessing it because of the cost implications for your business. Shifting from .NET Core 2.1 to .NET Core 3.1 will come with a price tag attached to it. After that, moving again from 3.1 to .NET 5 means more expenses. Instead of doing it in a roundabout way, you should simply eliminate the middleman and jump to .NET 5 directly.
Your applications will get necessary support well into the future and upgrading to .NET 6 will become easier. It won’t cost you too much, either.
If you aren’t using .NET Core 3.1 yet, then you’ll probably want to know a few things about it first. Here’s a list with descriptions of some of the features.
(1) Partial class support for Razor component
In .NET 3.1, developers will be able to generate Razor components as partial classes. They can author the code for any Razor component by using a code-behind file called a partial class instead of defining every piece of the code for the component in one file.
(2) Support for shared queues in HttpSysServer
Including the existing behaviour where the HttpSysServer used to create anonymous request queues, .NET 3.1 creators added an ability to build or attach to an existing and name HTTP.sys request queue. It will enable scenarios where the HTTP.Sys controller process owning the queue will become independent of the listener process. Naturally, it will be possible to preserve existing connections and enqueued requests between across-listener-process-restarts.
(3) Pass parameters to top-level components
Apps running on the Blazor Server can now pass parameters to the top-level components during the initial rendering process. Earlier, developers could only pass parameters to a top-level component with RenderMode.Static. By using .NET Core 3.1, developers will get support for both RenderMode.Server and RenderModel.ServerPrerendered. Every specified parameter will get serialized as JSON and included in the initial response.
(4) Breaking changes to SameSite cookies
.NET 3.1 updates the way SameSite cookies behave in ASP.NET Core. In doing so, those cookies will conform to the newest standards enforced by browsers.
The roadmap set by Microsoft for the future of .NET is becoming clearer by the minute. You should be ready because the company will keep bringing new updates loaded with new features, functionalities, and tools. Business companies can also open new paths with these systems. Industrialists and business owners can make use of Machine Learning, automation, and easier integration with internal and external business systems. They can also utilize web-assembly or WASM, support for Mac Catalyst from Apple, and .NET mobile development. You simply need to seek out a reliable and experienced development agency. Thanks to recent developments, your task won’t be too challenging, but it can be a bit time-consuming. You can’t afford to make the wrong choice just to save time. So, consider your options well before deciding.
