Can I use TransactionScope in business layer instead of using SQLiteTransaction in data provider ?

I would like to use the TransactionScope class in my business layer:

In AdminService class:

public void DeleteSchoolclass(Schoolclass schoolclass)
        {
            using (var trans = new TransactionScope())
            {
                adminProvider.DeleteSchoolclass(schoolclass.SchoolclassId);
                timetableProvider.DeleteTimeTableEntry(schoolclass.SchoolclassCode);

                trans.Complete();
            }             
        }

When I debug both Delete methods abouve the Transaction property of each Delete command object inside the dataprovider is NULL so it seems there is no transaction... How can I find out wether a Transaction is used or not?

Wen I debug the transactionscope object I dont find any Connection...

TransactionScope seems like magic...
