c# - Entity framework 6 transaction -

i need insert new rows in 2 of tables first table's auto generated id field 1 of field of second table .currently i'm using transaction inserting data. current code given below

        using (var context = new applicationdatabaseentities())         {             using (var transaction = context.database.begintransaction())             {                 try                 {                    foreach (var item in itemlist)                    {                     context.myfirstentity.add(item);                     context.savechanges();                      mysecondentity.myfirstentityid = item.id;                     context.mysecondentity.add(mysecondentity.myfirstentityid );                     context.savechanges();                     }                   transaction.commit();                 }                 catch (exception ex)                 {                     transaction.rollback();                     console.writeline(ex);                  }             }         } 

the above code working fine .my question is, correct way? mean if have 1000 or 2000 items insertion current code affect performance

code can improved implicit transaction:

foreach (var item in itemlist) {     context.myfirstentity.add(item);     mysecondentity.myfirstentity = item;     context.mysecondentity.add(mysecondentity); } context.savechanges(); 

note: instead of id i've used navigation property.
