Here's another one.  (Unsure if these are considered ontopic. If not, 
please let me know)

This small test program shows GC.Collect() + WeakReference working 
different on CLR
than they do on Mono. In mono, the WeakReference is still alive after 
in the clr, the WeakReference is no longer active.

using System;

public class MonoTest2
    public static void Main()
        var obj = new Version();
        WeakReference reference = new WeakReference(obj);
        obj = null;
        Console.WriteLine("reference.IsAlive: " + reference.IsAlive);
        //mono outputs true
        //clr outputs false

If people think this is a a bug, I'll file a report.

Bye, Lucas
