Chiamato appena prima che EF intenda chiamare RollbackAsync(CancellationToken).

Parametri
- transaction
- DbTransaction
Transazione.
- eventData
- TransactionEventData
Informazioni contestuali sulla connessione e sulla transazione.
- result
- InterceptionResult
Rappresenta il risultato corrente se esiste.
Questo valore sarà IsSuppressed impostato su true
se un intercettatore precedente ha eliminato l'esecuzione chiamando Suppress().
Questo valore viene in genere usato come valore restituito per l'implementazione di questo metodo.
- cancellationToken
- CancellationToken
Oggetto CancellationToken da osservare durante l'attesa del completamento dell'attività.
Restituisce
Se IsSuppressed è false
, EF continuerà come normale.
Se IsSuppressed è true
, EF elimina l'operazione che sta per eseguire.
Un'implementazione di questo metodo per qualsiasi intercettatore che non tenta di eliminare l'operazione consiste nel restituire il result
valore passato.
Eccezioni
Se CancellationToken viene annullato.
