Hi @Josef Szeliga,
Could you please provide any error message when you are trying to connect the loaclDB with SSMS?
You may also check the error message via Windows Event Viewer.
This installed the LocalDB feature of Express which does not install config mgr and is managed at the command line.
It's meant to be a very easy/quick way to have a lightweight sql server and is not meant to be used except locally and has a special connection string, hence configuration manager is not necessary.
If you want more features you can install the full Express edition or SQL Developer edition which is good for dev/test (non-production) usage.
Regards,
Zoe Hui
