Microsoft will end support for its .NET 8 and .NET 9 platforms on [November 10](https://github.com/dotnet/core/blob/main/release-notes/README.md), 2026. The company advises current users of those platforms to upgrade to [.NET 10](https://www.infoworld.com/article/4087667/microsofts-net-10-arrives-with-ai-runtime-and-language-improvements.html).

After November 10, Microsoft will no longer provide servicing updates, security fixes, or technical support for .NET 8 and .NET 9. “We recommend upgrading to [.NET 10](https://devblogs.microsoft.com/dotnet/announcing-dotnet-10/), which is an LTS (long term support) release supported through November 2028,” said Rahul Bhandari, Microsoft senior program manager in a June 29 [blog post](https://devblogs.microsoft.com/dotnet/dotnet-8-9-end-of-support/). “By upgrading, you will continue receiving security updates and servicing fixes to keep your applications protected.”

Apps can be upgraded to .NET 10 by changing the value of the `TargetFramework`

property in a project file to `net10.0`

. Development and hosting environments will need to be updated. This process is covered in detail in Microsoft’s article, “[Upgrade to a new .NET version](https://learn.microsoft.com/dotnet/core/install/upgrade).” .NET 10 can be downloaded from [dotnet.microsoft.com](https://dotnet.microsoft.com/en-us/download/dotnet/10.0).

[ .NET 8](https://www.infoworld.com/article/2335555/the-best-new-features-in-microsoft-net-8.html) was released November 14, 2023, and [.NET 9](https://www.infoworld.com/article/3603700/microsofts-net-9-arrives-with-performance-cloud-and-ai-boosts.html) was released November 12, 2024. [.NET 10](https://www.infoworld.com/article/3839444/the-key-new-features-in-net-10.html) became available November 11, 2025.

Microsoft said users of .NET 8 and .NET 9 could expect the following after November 10:

Also, beginning with a future servicing update for [Visual Studio 2022](https://www.infoworld.com/article/2270802/microsoft-visual-studio-2022-arrives.html), the .NET 8 and .NET 9 components will be marked as out of support. The arrival of the production release of [.NET 11](https://www.infoworld.com/article/4138881/under-the-hood-with-net-11-preview-1.html), meanwhile, is expected this November.
