How to disable Migration Verification during every DbContext initialization

问题

I am using CodeFirst approach in Entity Framework 6 and running my migration script manually to create Db and later update the changes in the schema.

I have noticed that every time the context is initialized, it checks for the "INFORMATION_SCHEMA.TABLES" and "MigrationHistory" metadata in the database. That adds 2 additional queries for each call.

This may not be a desirable situation for production environment. Is there a way to set it only once during application startup and these 2 process does not executed every time the DbContext is initialized.

Thanks

Finally solved it the following way and wish to share the solution:

class MyCustomDbConfiguration : DbConfiguration
        {
        public MyCustomDbConfiguration()
            {
            SetDatabaseInitializer(new NullDatabaseInitializer<MyDbContext>());
            }
        }
