If you are fighting against randoms System.Data.SqlClient.SqlException Timeout and you’re using sql express you can try to disable the Auto Close feature:

Right click on the database -> Properties

Those are a couple of errors I was having:

Excpetion:
Type: System.Data.SqlClient.

SqlException
Message: Timeout. Il tempo disponibile è scaduto prima del completamento dell’operazione o il server non risponde.
Stack trace:
