Entity Framework - Generic Transaction Methods -

we're using transactions entity framework, might switching other orm in future. what's best way implement following...

begintransaction();  //some update/insert/delete operations here entity.name = "joe"; savechanges();  endtransaction(); 

• we don't want use "using" statement
• we need work nested transactions

you can use transactionscope ... , can nest in try/catch/finally if want to, though "using" statement easier. there specific reason don't want use "using"? i've used both quite success, , supports nested transactions.
