This image contains the native dependencies needed by .NET. It does not include .NET. It is for self-contained applications.
Watch discussions for Docker-related .NET announcements.
Ubuntu Chiseled .NET images are a type of "distroless" container image that contain only the minimal set of packages .NET needs, with everything else removed. These images offer dramatically smaller deployment sizes and attack surface by including only the minimal set of packages required to run .NET applications.
Please see the Ubuntu Chiseled + .NET documentation page for more info.
The .NET Docker samples show various ways to use .NET and Docker together. See Building Docker Images for .NET Applications to learn more.
- .NET self-contained Sample - This sample builds and runs an application as a self-contained application.
.NET container images have several variants that offer different combinations of flexibility and deployment size. The Image Variants documentation contains a summary of the image variants and their use-cases.
.NET:
- dotnet: .NET
- dotnet/sdk: .NET SDK
- dotnet/aspnet: ASP.NET Core Runtime
- dotnet/runtime: .NET Runtime
- dotnet/monitor: .NET Monitor Tool
- dotnet/aspire-dashboard: .NET Aspire Dashboard
- dotnet/samples: .NET Samples
- dotnet/nightly/runtime-deps: .NET Runtime Dependencies (Preview)
.NET Framework:
- dotnet/framework: .NET Framework, ASP.NET and WCF
- dotnet/framework/samples: .NET Framework, ASP.NET and WCF Samples

Tags not listed in the table above are not supported. See the Supported Tags Policy. See the full list of tags for all supported and unsupported tags.
- Base Image Updates: Images are re-built within 12 hours of any updates to their base images (e.g. debian:bookworm-slim, windows/nanoserver:ltsc2022, etc.).
- .NET Releases: Images are re-built as part of releasing new .NET versions. This includes new major versions, minor versions, and servicing releases.
- Critical CVEs: Images are re-built to pick up critical CVE fixes as described by the CVE Update Policy below.
- Monthly Re-builds: Images are re-built monthly, typically on the second Tuesday of the month, in order to pick up lower-severity CVE fixes.
- Out-Of-Band Updates: Images can sometimes be re-built when out-of-band updates are necessary to address critical issues. If this happens, new fixed version tags will be updated according to the Fixed version tags documentation.
.NET container images are regularly monitored for the presence of CVEs. A given image will be rebuilt to pick up fixes for a CVE when:
- We detect the image contains a CVE with a CVSS score of "Critical"
- AND the CVE is in a package that is added in our Dockerfile layers (meaning the CVE is in a package we explicitly install or any transitive dependencies of those packages)
- AND there is a CVE fix for the package available in the affected base image's package repository.
Please refer to the Security Policy and Container Vulnerability Workflow for more detail about what to do when a CVE is encountered in a .NET image.
