Called immediately after EF calls ExecuteScalarAsync().

- command
- DbCommand
The command.
- eventData
- CommandExecutedEventData
Contextual information about the command and execution.
- result
- Object
The result of the call to ExecuteScalarAsync(). This value is typically used as the return value for the implementation of this method.
- cancellationToken
- CancellationToken
A CancellationToken to observe while waiting for the task to complete.
Returns
A Task providing the result that EF will use.
An implementation of this method for any interceptor that is not attempting to change the result
is to return the result value passed in, often using FromResult<TResult>(TResult)
Exceptions
If the CancellationToken is canceled.
Remarks
This method is still called if an interceptor suppressed execution of a command in ScalarExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Object>, CancellationToken). In this case, result is the result returned by ScalarExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Object>, CancellationToken).
