Lambda code examples for the SDK for .NET

Overview

Shows how to use the AWS SDK for .NET to work with AWS Lambda.

Lambda allows you to run code without provisioning or managing servers.

⚠ Important

  • Running this code might result in charges to your AWS account. For more details, see AWS Pricing and Free Tier.
  • Running the tests might result in charges to your AWS account.
  • We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see Grant least privilege.
  • This code is not tested in every AWS Region. For more information, see AWS Regional Services.

Code examples

Prerequisites

For prerequisites, see the README in the dotnetv3 folder.

Get started

Basics

Code examples that show you how to perform the essential operations within a service.

Single actions

Code excerpts that show you how to call individual service functions.

Scenarios

Code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

Run the examples

Instructions

For general instructions to run the examples, see the README in the dotnetv3 folder.

Some projects might include a settings.json file. Before compiling the project, you can change these values to match your own account and resources. Alternatively, add a settings.local.json file with your local settings, which will be loaded automatically when the application runs.

After the example compiles, you can run it from the command line. To do so, navigate to the folder that contains the .csproj file and run the following command:

dotnet run

Alternatively, you can run the example from within your IDE.

Hello Lambda

This example shows you how to get started using Lambda.

Learn the basics

This example shows you how to do the following:

  • Create an IAM role and Lambda function, then upload handler code.
  • Invoke the function with a single parameter and get results.
  • Update the function code and configure with an environment variable.
  • Invoke the function with new parameters and get results. Display the returned execution log.
  • List the functions for your account, then clean up resources.

Create a serverless application to manage photos

This example shows you how to create a serverless application that lets users manage photos using labels.

Create an application to analyze customer feedback

This example shows you how to create an application that analyzes customer comment cards, translates them from their original language, determines their sentiment, and generates an audio file from the translated text.

Transform data with S3 Object Lambda

This example shows you how to transform data for your application with S3 Object Lambda.

Tests

⚠ Running tests might result in charges to your AWS account.

To find instructions for running these tests, see the README in the dotnetv3 folder.
