Why is the external “final” not fulfilled when the internal “trick” is thrown?

Question

I wrote a simple program to test the theory that the finally block will always be executed no matter what. But what I see from the pgm below is that the control never enters an external final block.

I tried to make F5 as well as Ctrl-F5 in Visual Studio, and this is the same result.

Can someone explain why I see this behavior?

The output in the console window:

internal catch

internal finally

external catch

raw execution:

.. and then the application crashes

public class Program
{
    static void Main()
    {
        try
        {
            try
            {
                string s = null;
                s.ToString();
            }
            catch
            {
                Console.WriteLine("inner catch");
                throw;
            }
            finally
            {
                Console.WriteLine("inner finally");
            }

            return;
        }
        catch
        {
            Console.WriteLine("outer catch");
            throw;
        }
        finally
        {
            Console.WriteLine("outer finally");
        }
    }
}
