+Summary: set null to WeakReference.Target doesn't work
+
+Description of Problem:
+set null to WeakReference.Target doesn't work
+
+Steps to reproduce the problem:
+I execute such code in C# console project:
+using System;
+
+namespace Mono_GC {
+  class A{}
+
+  class Class1 {
+
+    [STAThread]
+    static void Main(string[] args) {
+
+      A a = new A();
+      WeakReference weak = new WeakReference(a);
+      Console.WriteLine("weak.Target = " + a);
+      if(weak.Target != null)
+        Console.WriteLine("weak.Target != null");
+      else
+        Console.WriteLine("weak.Target == null");
+
+      weak.Target = null;
+      Console.WriteLine("weak.Target = null");
+      if(weak.Target != null)
+        Console.WriteLine("test failed");
+      else
+        Console.WriteLine("test passed");
+
+      Console.WriteLine("Weak reference test has been finished.");
+    }
+  }
+}
+
+Actual Results:
+weak.Target = Mono_GC.A
+weak.Target != null
+weak.Target = null
+test failed
+Weak reference test has been finished.
+
+Expected Results:
+weak.Target = Mono_GC.A
+weak.Target != null
+weak.Target = null
+test passed
+Weak reference test has been finished.
+
+How often does this happen? 
+every run
