NLog: Force BufferingTargetWrapper to empty on AppDomain UnhandledException

Question

I have NLog configured in my application to to use the BufferingTargetWrapper for sending emails with the MailTarget.

The problem I'm running into is I can not find a way to force NLog to empty the BufferingTargetWrapper before the application exits from Unhandled Exceptions.

I tried calling LogManager.Flush() and LogManager.DisableLogging() from the Current App Domain's UnhandledException Event but it does not seam to work.

What would I need to do to make it send the emails?

Are you using a PostFilteringWrapper? I'd really want to see your .nlog or programmatic configuration. — Mike Post, Mar 14 '10 at 11:01
I think there is either an extra thread running with the buffer, which doesn't get any timeslice or a pending timer which would need (some) time. did you try some Threading.Thread.Speep(x) ? — ralf.w., Apr 05 '11 at 18:39

you can call the BufferingTargetWrapper and force it to write the logs. Its strange that the LogManger.Flush doesn't work.

var buffWapper =
            LogManager.Configuration.FindTargetByName("BufferingTargetWrapper") as BufferingTargetWrapper;
        if (buffWapper != null)
            buffWapper.Flush();

or

var buffWapper =
            LogManager.Configuration.FindTargetByName("BufferingTargetWrapper") as BufferingTargetWrapper;
        if (buffWapper != null)
        {
            buffWapper.BufferSize = 1;
            buffWapper.Flush();
        }
