AWS Lambda now supports .NET 8 as both a managed runtime and container base image. With this release, Lambda developers can benefit from .NET 8 features including API enhancements, improved Native Ahead of Time (Native AOT) support, and improved performance. .NET 8 supports C# 12, F# 8, and PowerShell 7.4. You can develop Lambda functions in .NET 8 using the AWS Toolkit for Visual Studio, the AWS Extensions for .NET CLI, AWS Serverless Application Model (AWS SAM), AWS CDK, and other infrastructure as code tools. The .NET 8 runtime is built on the Amazon Linux 2023 (AL2023) minimal container image, providing a smaller deployment footprint and updated versions of common libraries. The operating system has been upgraded to include glibc 2.34 and OpenSSL 3. Microdnf is now used as the package manager instead of yum. Overall, the introduction of .NET 8 for AWS Lambda offers developers a more efficient and feature-rich environment for creating serverless applications.
