AWS Cloud Adds .NET Core 2.0 Support for C# Coding of Lambda Functions

Amazon Web Services Inc. (AWS) this week said .NET-centric developers using its cloud platform to write AWS Lambda functions can now do so in C# while leveraging .NET Core 2.0 libraries.

AWS Lambda are the foundation of Amazon's "serverless computing" service, allowing developers to create functions that are executed -- typically triggered by events -- without the need to manage or provision 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.
