Announcing the end of support for the AWS SDK for .NET version 2

On May 1st, 2021, the AWS SDK for .NET version 2 (v2) will reach the end of support. After this date it will no longer receive updates or releases, including critical bugs or security updates. Previously published releases will continue to be available via NuGet. The code will remain on GitHub, but the repository may be archived. Once .NET SDK v2 reaches the end of support, you many continue using it at your discretion.

If you are running applications using .NET SDK v2, we recommend that you migrate your applications to the latest major version – AWS SDK for .NET version 3 (v3). The .NET SDK v3 is redesigned to be completely modular. You no longer have to add the entire AWS SDK for .NET to your application and can only add assemblies for the AWS services your application uses. Please note that version 3 of .NET SDK included a few breaking changes from version 2, for detailed migration instructions please see our Migration Guide.

You may also consider the latest release of .NET SDK v3, version 3.5, which transitions support for all non-Framework versions of the SDK to .NET Standard 2.0. For additional migration instructions please see our blog post and “Migrating to version 3.5 of the AWS SDK for .NET” guide.
