## What it is
A collection of NuGet libraries, CLI tools, and project templates from AWS for building AWS Lambda functions with .NET. It includes event type packages, deployment tooling, ASP.NET Core integration, and test utilities.

## Use cases
- write aws lambda functions in c#
- deploy .net lambda functions from the cli
- handle api gateway events in lambda
- run asp.net core apps on lambda
- unit test lambda handlers
- scaffold lambda project templates

## When to choose
- building serverless applications on AWS with .NET
- you need typed event classes for AWS service triggers
- deploying and packaging .NET Lambda functions via dotnet CLI

## When to avoid
- running lambdas in other languages
- using non-AWS serverless platforms
- general-purpose .NET development outside Lambda

## Facets
- artifact type: library
- maturity: active
- function: sdk, cli, developer-tools, middleware, testing
- domain: cloud-computing, developer-tools, backend, apis
- platform: dotnet, cloud, serverless, cli
- tags: aws-lambda, nuget-packages, dotnet-templates, aspnet-core, event-handling, blueprints, serverless
