c# - How to detect when main thread terminates?

Question

What I need to know:

I would like to detect when a the main thread (process?) terminates so that I can ensure certain actions are performed before it is terminated.

What I have found myself:

I found the events AppDomain.DomainUnload and AppDomain.ProcessExit. AppDomain.DomainUnload seems to work with non-applications like MbUnit. AppDomain.ProcessExit seems to work with applications but there is a 3 second time limit which I really don't like. Is there more ways to detect when an AppDomain / process terminates?

Background:

I am looking for such an event to ensure my log is persistet to file when the application terminates. The actual logging runs on another thread using a producer-consumer pattern where it is very likely that log entries might queue up in memory and I need to ensure this queue is saved to file when the application terminates.

Is there anything else I should be aware of?

Update:

Changed the above to reflect what I have found out myself. I am not happy with the 3 second time limit during ProcessExit. The MSDN documentation does say though that it can be extended:

The total execution time of all ProcessExit event handlers is limited, just as the total execution time of all finalizers is limited at process shutdown. The default is three seconds, which can be overridden by an unmanaged host.

Does anyone know how to override the default?

More ideas are also highly appreciated!

You should have an entry point for your application. Normally you can do there some logging when all tasks are terminated:

static void Main()
{
  try
  {
    Application.Run( .... );
  }
  finally
  {
    // logging ...
  }
}
