c# - Static Finalizer

Question

What is the right way to perform some static finallization?

There is no static destructor. The AppDomain.DomainUnload event is not raised in the default domain. The AppDomain.ProcessExit event shares the total time of the three seconds (default settings) between all event handlers, so it's not really usable.

Herfried Wagner has written an excellent article explaining how to implement this – alas, in German (and VB). Still, the code should be understandable.

I've tried it:

static readonly Finalizer finalizer = new Finalizer();

sealed class Finalizer {
  ~Finalizer() {
    Thread.Sleep(1000);
    Console.WriteLine("one");
    Thread.Sleep(1000);
    Console.WriteLine("two");
    Thread.Sleep(1000);
    Console.WriteLine("three");
    Thread.Sleep(1000);
    Console.WriteLine("four");
    Thread.Sleep(1000);
    Console.WriteLine("five");
  }
}

It seems to work exactly the same way as the AppDomain.ProcessExit event does: the finalizer gets ca. three seconds...
