Definición

Parte de la información hace referencia a la versión preliminar del producto, que puede haberse modificado sustancialmente antes de lanzar la versión definitiva. Microsoft no otorga ninguna garantía, explícita o implícita, con respecto a la información proporcionada aquí.
Se llama inmediatamente después de llamar a EF.ExecuteScalarAsync()

- command
- DbCommand
El comando.
- eventData
- CommandExecutedEventData
Información contextual sobre el comando y la ejecución.
- result
- Object
Resultado de la llamada a ExecuteScalarAsync(). 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
Que Task proporciona el resultado que EF usará.
Una implementación de este método para cualquier interceptor que no intente cambiar el resultado es devolver el result valor pasado, a menudo usando FromResult<TResult>(TResult)
Excepciones
Si se cancela CancellationToken.
Comentarios
Se sigue llamando a este método si un interceptor suprimió la ejecución de un comando en ScalarExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Object>, CancellationToken). En este caso, result es el resultado devuelto por ScalarExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Object>, CancellationToken).
