Can the caller ignore async WCF call result?

I'm sure this must have been asked and answered, but I can't find it...

I have a WCF service with this interface:

[ServiceContract(Namespace = WcfNamespace.MyNamespace)]
public interface ILogging
{
    [OperationContract(IsOneWay = true)]
    void LogInfo(string message);
}

In my (.NET 3.5) client application, I want to ignore any failure that happens during the call to LogInfo and I don't want to block, not even on the network transport.
Therefore, I'm thinking I should use one of the async patterns in my client. However, I can't figure out if there is any difference in how "ignore-the-result-friendly" the "event-based" or the "begin-end" patterns are. Is there a difference in this sense?
Or do you always have to implement a completed event or call End* anyway in order to not leak resources? (I vaguely recall reading something like that by either Skeet or Lippert)

You don't need to implement any *Completed events if you're using the event-based async pattern, so that's an option. If you use the begin/end pattern, you should call the End* operation, and wrap it in a try/empty catch if you want to really ignore anything.
