Future Plans and Limitations for .NET Core 2.1 on Azure

We are currently running applications on .NET Core 2.1 on some of our Azure servers. As we plan to update to a more recent .NET version, we want to prioritize and schedule this update effectively.

I have a couple of questions regarding the use of the outdated .NET Core 2.1 on Azure:

  1. Are there any plans from Microsoft or Azure to stop or limit support for services running on .NET Core 2.1?
  2. What limitations or issues might we face if we continue using .NET Core 2.1 on Azure?

Any insights or guidance would be greatly appreciated!

Thanks!

    Are there any plans from Microsoft or Azure to stop or limit support for services running on .NET Core 2.1?

    You might keep an eye on https://azure.microsoft.com/en-us/updates/. Not likely that your existing applications will be impacted until an announcement is made to the public.

    What limitations or issues might we face if we continue using .NET Core 2.1 on Azure?

    The limitations of using end-of-life frameworks are well documented in previous announcements, like this that "we'll no longer provide patches or customer service for .NET Core xxx". Similar statements can be found in .NET 5/6/7 end-of-life announcements as well.

    The main issue is that none of the known security vulnerabilities are being fixed. Also as unsupported, if you run into an issue or a change in azure breaks your application, you will get no support until you upgrade.
