.NET Core Lifecycle News

.NET Core 2.2 reached end of life on December 23, 2019. This means .NET Core 2.2 is no longer supported and updates will no longer be provided. We recommend moving to .NET Core 3.1, our long term support (LTS) release.

.NET Core 3.0 will reach end of life on March 3, 2020 which is 3 months after the release of .NET Core 3.1. You can view the Microsoft Support for .NET Core for more information about life-cycle of each product.

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