Se llama justo antes de que EF intente llamar OpenAsync()a .

Parámetros

connection
DbConnection

La conexión.

eventData
ConnectionEventData

Información contextual sobre la conexión.

result
InterceptionResult

Representa el resultado actual si existe uno. Este valor se establecerá IsSuppressedtrue en si algún interceptor anterior suprimió la ejecución mediante una llamada a Suppress(). Este valor se usa normalmente como valor devuelto para la implementación de este método.

cancellationToken
CancellationToken

Que CancellationToken se debe observar mientras se espera a que se complete la tarea.

Devoluciones

Task<InterceptionResult>
ValueTask<InterceptionResult>

Si IsSuppressed es false, EF continuará como normal. Si IsSuppressed es true, EF suprimirá la operación que estaba a punto de realizar. Una implementación de este método para cualquier interceptor que no intente suprimir la operación es devolver el result valor pasado.

Excepciones

OperationCanceledException

Si se cancela CancellationToken.
