Taken from https://xamarin.desk.com/agent/case/19109...

I receive the following exception when the finalizer of one of my classes is called:


{System.InvalidOperationException: Handle is not allocated

According to this article:

It should not throw an exception anymore. Could you look at it please?

Thanks,
