.net core 3.1 will still be working after 3 dec 2022?

Question

Hi All,

I heard that microsoft .net core 3.1 extended support will end at 3 dec 2022 (https://azure.microsoft.com/en-us/updates/extended-support-for-microsoft-net-core-31-will-end-on-3-december-2022/) and unfortunately, i have API and azure functions that still use .net core 3.1, and cannot migrate it soon or before 3 dec 2022. does it mean after 03 december 2022, all .net 3.1 applications will drop dead after 3 dec 2022, or they can still run, but if there is a bug in .net 3.1 core, microsoft will not longer provide patches

Many thanks

Hello @arif liminto

On 3 December 2022, extended support for Microsoft .NET Core 3.1 will end. After that date, your applications that are hosted on Functions or WebApps will continue to run and your applications will not be impacted. However, Microsoft will no longer provide patches, or online technical assistance. or customer service for .NET Core 3.1.

You are right if there is a bug in .net 3.1 core, microsoft will not longer provide patches as use of out-of-support .NET versions may put your applications, application data, and computing environment at risk.

You should check with your security, financial or legal departments to check for compliance risks of running on unsupported software.

Answer 3

So is .net core dead as a stand-alone framework?

Has it been integrated into .net v7?
