        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options):base(options)
        {
   
        }

add-migration MigrationFIleName

Migration File created with the extra snapshot file. you can check in the migration folder for more details.

Once the migration file is created then only auto migration code may run.

           try
            {
                if (_db.Database.GetPendingMigrations().Count() > 0)
                {
                    _db.Database.Migrate();
                }
    
       
            }catch(Exception ex)
            {

            }

Try the above code when the program starts.

Register and run the program from the program.cs

SeedDataBase(); in the pipeline of program.cs

Final code to start migration:

void SeedDataBase()
{
    using ( var scope= app.Services.CreateScope())
    {
        var dbInitializer = scope.ServiceProvider.GetRequiredService<IDbInitializer>();
        dbInitializer.Initialize();
    }
}
