However, you can build for more TargetFrameworks by setting AdditionalBuildTargetFrameworks property.
(from #31823)
Can we change the config system so that .NET Framework TFMs - if set in the project - are built as well, IF the tooling to build is already restored? I don't see a reason why we would filter them out if the vertical is already restored.
This would make it easier to build and run tests on .NET Framework configurations.
