Where is the database stored when using EF Core under SQL Server?

Question

C++ / C#

Let's say in the context for the database there is such a method:

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            optionsBuilder.UseSqlServer("Server=(localdb)\\mssqllocaldb;Database=database_01;Trusted_Connection=True;");
        }

Where, based on this record, the file itself from the database can be saved and what other additional information is needed?

PS There is no database file in the folder with the executable itself

Answer 1

The *.mdf file with the base must be in the user's local folder.
C:\Users\%USERNAME%\database_01.mdf
or:
C:\Users\%USERNAME%\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\MSSQLLocalDB
