2.1 declared LTS

As mentioned in a previous blog post, we have been working toward declaring .NET Core 2.1 as LTS. With the August Update, we’re pleased to announce that 2.1.3 begins the .NET Core 2.1 LTS lifecycle. We’ll continue to update 2.1 with important fixes to address security and reliability issues as wells as add support for new operating system versions. Details on the .NET Core lifecycle can be seen in the .NET Core support policy.

What’s covered?

The LTS designation covers all packages referenced by Microsoft.NETCore.App and Microsoft.AspNetCore.App. To ensure that applications running on 2.1 remain on the LTS supported updates, it’s important to reference these ‘meta-packages’ rather than individual ‘loose’ packages. This will enable the applications to properly utilize 2.1 updates when they are released and installed.

The .NET Core SDK is not included as part of the LTS designation. SDK fixes will continue to be released in the latest version ‘train’ which supports maintaining and building applications for .NET Core 2.1.

See .NET Core Supported OS Lifecycle Policy to learn about Windows, macOS and Linux versions that are supported for each .NET Core release.
