.NET Core 2.1 Support Added to AWS Lambda

The Lambda service on Amazon Web Services Inc. (AWS) cloud now supports .NET Core 2.1, the company announced this week.

AWS Lambda lets developers run programming code -- in this case C# -- without the need to provision or manage servers, often in response to event triggers.

Those event triggers and server functions can now be written with the latest version of .NET Core, Microsoft's modularized, cross-platform and open source take on the .NET Framework, or more properly, an implementation of the newer .NET Standard.

AWS Lambda supported .NET Core 2.0 early this year, and support for the runtime for other coding tools was announced last summer.

Now, AWS Lambda supports .NET Core 2.1, which will be Microsoft's Long Term Support (LTS) offering going forward. However, there was a flaw discovered in .NET Core 2.1 that will extend the life of .NET Core 2.0.

"Microsoft will end its support for .NET Core 2.0 at the beginning of October, 2018," AWS said in a post yesterday (July 9). "At that time, .NET Core 2.0 AWS Lambda functions will be subject to deprecation per the AWS Lambda Runtime Support Policy. After three months, you will no longer be able to create AWS Lambda functions using .NET Core 2.0, although you will be able to update existing functions. After six months, update functionality will also be disabled."

AWS said developers will now be able to take advantage of new features introduced in .NET Core 2.1, including a more performant HTTP client. "This is particularly important when integrating with other AWS services from your AWS Lambda function," the post said. Other new features highlighted in the post include new Span<T> and Memory<T> language features.

More information is provided in another blog post. "The easiest way to get started is with the AWS Toolkit for Visual Studio which includes project templates for individual C# Lambda functions, full C# serverless applications, and tools to publish both project types to AWS," it said.

The .NET Core 2.1 runtime is now available in all regions where Lambda is available.
