AWS Lambda Now Supports .NET Core 2.0
Amazon Web Services Inc. (AWS) announced new support for creating Lambda functions with the C# programming language and .NET Core 2.0 libraries.
AWS Lambda is the cloud giant's "serverless computing" service, which lets developers create functions that are executed -- typically in response to events -- without the need to provision or manage specific servers.
.NET Core 2.0 is a general purpose development platform maintained by Microsoft and the .NET community on GitHub, providing a modular, open source, cross-platform implementation of .NET, as opposed to the monolithic and Windows-only Microsoft .NET Framework. It can be used to build Windows, Mobile and Web applications for Windows, Linux and OS X platforms.
Along with the related .NET Standard 2.0, it's designed to standardize API usage across .NET-based projects.
AWS said the easiest way to get started with its new .NET Core 2.0 support for authoring Lambda functions is to use the AWS Toolkit for Visual Studio and its built-in project templates for individual C# Lambda functions, complete C# serverless applications and tools for publishing both types of projects to the AWS cloud platform.
"To manually create a C# Lambda function, you simply specify the Lambda runtime parameter as dotnetcore2.0 and upload the ZIP of all NuGet dependencies as well as your own published DLL assemblies through the AWS CLI or AWS Lambda console," AWS said in a blog post this week.
"You can also use the AWS Serverless Application Model (SAM) to deploy and manage serverless applications authored in C#. Support for testing C# functions locally with SAM Local is coming soon. If you have existing C# functions running on 1.0, you can switch to the new runtime by updating your .NET project’s target framework moniker to netcoreapp2.0 and re-deploying the function with the new dotnetcore2.0 runtime."
Support for the .NET Core 2.0 runtime is available in all AWS regions where AWS Lambda is available. AWS Lambda developer guidance can be found here.
