What is the lifetime of DbContext?-CodePudding

On Startup.cs, the application establishes connection with the database.

services.AddDbContext<DataContext>(opt=>
  opt.UseSqlLite(_config.GetCinnectionString(‘DefaultConnectionString’));
});

This opt object of the now established database connection is injected as options to the DataContext class-

public class DataContext:DbContext
{
   public DataContext(DbContextOptions options):base(options)
}

And further on, whenever DataContext is referred to on different classes like

public class SomeMethod
{
   private readonly DataContext _context;
   SomeMethod(DataContext context)
   {
     _context = context:
   }
}

The execution flow is - SomeMethod=>DataContext(which gets its options object from Startup) referring to the applications session with the database.

I hope we are not establishing a new connection with the database each time we are referring to DataContext.

Would love to read the answers. And please feel free to add details/intricacies to the flow as I haven’t been able to find many answers regarding this.

Check here everything for EF Core

The default it's scoped.
