+Summary: BinaryFormatter not calling IObjectReference.GetRealObject on an Hashtable key 
+
+Description of Problem:
+BinaryFormatter is not calling IObjectReference.GetRealObject on an
+Hashtable key object
+
+Steps to reproduce the problem:
+1. Checkout the attached code
+2. mcs BinaryFormatterBug.cs
+3. mono BinaryFormatter.exe
+
+Actual Results:
+System.Reflection.TargetInvocationException: Exception has been thrown by
+the target of an invocation. ---> System.ArgumentNullException: null key
+Parameter name: key
+
+Expected Results:
+No exceptions
+
+How often does this happen? 
+Always... when using an Hashtable to store a key that is deserialized using
+a helper class that implements IObjectReference
+
+Additional Information:
+SoapFormatter works fine in this situation
+Also, Mono's BinaryFormatter does not complaint if we serialize something
+like this:
+class A : ISerializable {}
+
+
+However, in MS .NET we must have:
+[Serializable] class A : ISerializable {}
