AWS Lambda recently added support for .NET 6, as both a managed runtime and a container base image. The new runtime introduces new .NET language features and performance optimizations, improves logging and simplifies function definition using top-level statements, according to InfoQ.

.NET 6 is the latest long-term support (LTS) release of .NET and will be supported for security and bug fixes until November 2024. AWS will automatically apply updates to the .NET 6 managed runtime and to the AWS-provided .NET 6 base image, as they become available.

The .NET 6 runtime is available in all Regions where Lambda is available, except for the AWS China Regions, as noted in an AWS publication.
