Repository for the AWS NuGet packages and Blueprints to support writing AWS Lambda functions using .NET Core.
For a history of releases view the release change log
Our intention is to keep a regular patch and update cycle to ensure Lambda developers have access to the currently supported patch of each major version of .NET Core. Given the development and deployment effort, our target is to have most rollouts complete in less than a month. We do not expect it to be less than one week. This enables us to ensure high quality deployments. We will give special attention to any versions that contain security updates critical to .NET Core in AWS Lambda.
The table below shows the currently supported patch of each major version of .NET Core in AWS Lambda, the next version(s) we plan on deploying, and the latest version released by Microsoft. These are subject to change and we'll keep this table as up-to-date as possible.
| Version | Currently Supported Patch | In Development Queue | Latest Microsoft Release |
|---|---|---|---|
| 1.0 | 1.0.13 | 1.0.15 | 1.0.15 |
| 2.0 | 2.0.9 | 2.0.9 | |
| 2.1 | 2.1.8 | 2.1.10 | 2.1.10 |

- In this episode we create a "Not Hotdog" clone from Silicon Valley (HBO) called "SchnitzelOrNot" with .NET and AWS. For this we use AWS Lambda with .NET Core, S3, and Amazon Rekognition.
This packages in this folder contains classes that can be used as input types for Lambda functions that process various AWS events.
These are the packages and their README.md files:
- Amazon.Lambda.APIGatewayEvents - README.md
- Amazon.Lambda.ApplicationLoadBalancerEvents - README.md
- Amazon.Lambda.CloudWatchLogsEvents - README.md
- Amazon.Lambda.CognitoEvents - README.md
- Amazon.Lambda.ConfigEvents - README.md
- Amazon.Lambda.DynamoDBEvents - README.md
- Amazon.Lambda.LexEvents - README.md
- Amazon.Lambda.KinesisAnalyticsEvents - README.md
- Amazon.Lambda.KinesisEvents - README.md
- Amazon.Lambda.KinesisFirehoseEvents - README.md
- Amazon.Lambda.S3Events - README.md
- Amazon.Lambda.SimpleEmailEvents - README.md
- Amazon.Lambda.SNSEvents - README.md
- Amazon.Lambda.SQSEvents - README.md
Package adds commands to the dotnet cli that can be used manage Lambda functions including deploying a function from the dotnet cli. For more information see the README.md file for Amazon.Lambda.Tools.
As of September 10th, 2018 Amazon.Lambda.Tools has migrated to be .NET Core Global Tools. As part of the migration the version number was set to 3.0.0.0
To install Amazon.Lambda.Tools use the dotnet tool install command.
dotnet tool install -g Amazon.Lambda.Tools
To update to the latest version of Amazon.Lambda.Tools use the dotnet tool update command.
dotnet tool update -g Amazon.Lambda.Tools
To migrate an existing project away from the older project tool, you need to edit your project file and remove the DotNetCliToolReference for the Amazon.Lambda.Tools package. For example, let's look at an existing Lambda project file.
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>netcoreapp2.1</TargetFramework>
<GenerateRuntimeConfigurationFiles>true</GenerateRuntimeConfigurationFiles>
<-- The new property indicating to AWS Toolkit for Visual Studio this is a Lambda project -->
<AWSProjectType>Lambda</AWSProjectType>
</PropertyGroup>
<ItemGroup>
<-- This line needs to be removed -->
<DotNetCliToolReference Include="Amazon.Lambda.Tools" Version="2.2.0" />
</ItemGroup>
<ItemGroup>
<PackageReference Include="Amazon.Lambda.Core" Version="1.0.0" />
<PackageReference Include="Amazon.Lambda.Serialization.Json" Version="1.3.0" />
</ItemGroup>
</Project>To migrate this project, you need to delete the DotNetCliToolReference element, including Amazon.Lambda.Tools. If you don't remove this line, the older project tool version of Amazon.Lambda.Tools will be used instead of an installed Global Tool.
The AWS Toolkit for Visual Studio before .NET Core 2.1 would look for the presence of Amazon.Lambda.Tools in the project file to determine whether to show the Lambda deployment menu item. Because we knew we were going to switch to Global Tools, and the reference to Amazon.Lambda.Tools in the project was going away, we added the AWSProjectType property to the project file. The current version of the AWS Toolkit for Visual Studio now looks for either the presence of Amazon.Lambda.Tools or the AWSProjectType set to Lambda. Make sure when removing the DotNetCliToolReference that your project file has the AWSProjectType property to continue deploying with the AWS Toolkit for Visual Studio.
Package makes it easy to run ASP.NET Core Web API applications as Lambda functions. For more information see the README.md file for Amazon.Lambda.AspNetCoreServer.
Package includes test implementation of the interfaces from Amazon.Lambda.Core and helper methods to help in locally testing. For more information see the README.md file for Amazon.Lambda.TestUtilities.
Blueprints in this repository are .NET Core Lambda functions that can used to get started. In Visual Studio the Blueprints are avalible when creating a new project and selecting the AWS Lambda Project.
New .NET Core projects can be created with the dotnet new command. By installing the Amazon.Lambda.Templates NuGet package the AWS Lamdba blueprints can be created from the dotnet new command. To install the template execute the following command:
dotnet new -i Amazon.Lambda.Templates::*
The ::* on the end of the command indicates the latest version of the NuGet package.
To see a list of the Lambda templates execute dotnet new lambda --list
> dotnet new lambda --list

To get details about a template, you can use the help command.
dotnet new lambda.EmptyFunction --help
Template Instantiation Commands for .NET Core CLI.
Lambda Empty Function (C#)
Author: AWS
Options:
-p|--profile The AWS credentials profile set in aws-lambda-tools-defaults.json and used as the default profile when interacting with AWS.
string - Optional
-r|--region The AWS region set in aws-lambda-tools-defaults.json and used as the default region when interacting with AWS.
string - Optional
The templates take two optional parameters to set the profile and region. These values are written to the aws-lambda-tools-default.json.
To create a function, run the following command
dotnet new lambda.EmptyFunction --name BlogFunction --profile default --region us-east-2
The Yeoman generators have been deprecated in favor of the new dotnet new templates. They will not be migrated from the older project.json based project system.
