The NRE specifically is in MSBuildStaticGraphRestore.GetPackageSpec. The caller iterates each ProjectWithInnerNodes and calls GetPackageSpec(project.OuterProject), but project.OuterProject is null for the Dep\Dep.csproj entry.
If any of the following is changed, it works:
- Non-static graph restore
- Remove the
SetTargetFramework metadata from Broken\Broken.csproj
- Migrate
Broken\Broken.csproj to SDK-style
