Chiamato appena prima che EF intenda chiamare BeginTransaction(IsolationLevel).

Parametri
- connection
- DbConnection
Connessione.
- eventData
- TransactionStartingEventData
Informazioni contestuali sulla connessione e sulla transazione.
- result
- InterceptionResult<DbTransaction>
Rappresenta il risultato corrente se esiste.
Questo valore sarà HasResult impostato su true
se un intercettatore precedente ha eliminato l'esecuzione chiamando SuppressWithResult(TResult).
Questo valore viene in genere usato come valore restituito per l'implementazione di questo metodo.
Restituisce
Se HasResult è false, l'EF continuerà come normale.
Se HasResult è true, EF elimina l'operazione che sta per eseguire e usare Result .
Un'implementazione di questo metodo per qualsiasi intercettatore che non tenta di modificare il risultato consiste nel restituire il result
valore passato, spesso usando FromResult<TResult>(TResult)
