What does the end of support for .NET 5 mean to you?

.NET 5 will reach end of support in just a few months. After the May Update, this version of .NET will no longer see maintenance, security updates, or receive technical support. Fortunately, upgrading to .NET 6 to stay supported isn’t a big deal.

That said, that doesn’t mean apps built on .NET 5 will suddenly stop working in May. However, since .NET 5 is not an LTS release, it was only supposed to be officially supported for 18 months or 6 months after the release of the next version, in this case .NET 6.

Upgrade to .NET 6.0

As always, before upgrading, I recommend checking for breaking changes. You can check the compatibility of your applications by going to the official Microsoft documentation on the subject.

The next thing I like to do is make sure my development environment and tools are up to date and ready. Check out the links below for more information and links on how to update yourself.

The last step would be to make sure you have a backup of your code before proceeding with the upgrade. Once you’ve made sure you have something to turn to in the event of a problem, the process is very simple!

Open your project file, replace .net5 with .net6. and you are ready to get started with .net6 on your existing application.

It might seem impossible to keep your apps up to date, the main reason my team tracks them is for security threats. Your best bet to stay safe is to use the latest supported version. You never want to be in a situation where you rush an upgrade because the fix you need isn’t available in the version of the framework you’re using.
