Parâmetros

connection
DbConnection

A conexão.

eventData
TransactionStartingEventData

Informações contextuais sobre conexão e transação.

result
InterceptionResult<DbTransaction>

Representa o resultado atual se houver um. Esse valor terá HasResult definido como true se algum interceptador anterior suprimisse a execução chamando SuppressWithResult(TResult). Esse valor normalmente é usado como o valor retornado para a implementação desse método.

Retornos

InterceptionResult<DbTransaction>

Se HasResult for false, o EF continuará normalmente. Se HasResult for true, o EF suprimirá a operação que estava prestes a executar e usar Result . Uma implementação desse método para qualquer interceptador que não está tentando alterar o resultado é retornar o result valor passado, muitas vezes usando FromResult<TResult>(TResult)
