public RegistryInfo registry { get; }

This value always returns a registry, even if the package's source is not PackageSource.Registry (such as an embedded package or a Git dependency). In that case, this value is set to the closest registry match even if the package isn't actually on that registry. For example, if your project uses a scoped registry with the scope, and your embedded package is named , this property will be the RegistryInfo from the matching scoped registry.

For more information, see "Managing scoped registries for a project" in Scoped Registries.
