A complete guide to building container images from a .NET 11 app with no Dockerfile: the PublishContainer target, ContainerRepository and ContainerImageTags, base image selection through ContainerBaseImage and ContainerFamily, pushing to a registry and how authentication resolves, multi-arch OCI image indexes, the non-root default user, entrypoint control, tarball output for scanners, and the cases where you still need a Dockerfile.
