## What it is
The official Docker container images for .NET, including SDK, ASP.NET Core runtime, runtime, runtime-deps, and monitoring tool images. Maintained by Microsoft, these images provide the standard base images for building and running .NET applications in containers.

## Use cases
- containerize a .NET application
- find the official .NET SDK docker image
- build multi-stage dockerfiles for ASP.NET Core apps
- run .NET apps in Kubernetes
- create minimal container images for .NET
- dockerize a C# web API

## When to choose
- you need trusted, Microsoft-maintained base images for .NET containers
- you want regularly updated images for every .NET release
- you need variants for different architectures, distros, and image sizes

## When to avoid
- you need container images for a non-.NET runtime
- you want a custom image build pipeline rather than official prebuilt images

## Facets
- artifact type: infra-config
- maturity: stable
- function: container-runtime, deployment, developer-tools
- domain: cloud-computing, backend
- platform: windows, cross-platform, cloud
- tags: dotnet, docker-images, container-images, official-images, aspnet-core, dotnet-sdk, microsoft, containers, devops, docker, linux
