+Summary: The ObjectStateFormatter doesn't use type converters when availables, this may break code already running on MS implementation
+
+Description of Problem:
+When handling non-optimized types, the ObjectStateFormatter doesn't use 
+type converters when availables, it just feeds the type to a 
+BinaryFormatter which may cause an exception to be thrown if the type is 
+not marked as serializable.
+
+Steps to reproduce the problem:
+1. Define a dummy type and a dummy type converter. DO NOT mark the dummy 
+type with the Serializable attribute. DO NOT implement the ISerializable 
+interface also.
+2. Assign the dummy type converter to the dummy type by using the 
+TypeConverter attribute.
+3. Save an instance of the dummy type to viewstate.
+
+Actual Results:
+A SerializationException exception will be thrown. This is because the 
+ObjectStateFormatter is not using the type converter and it is just 
+feeding the type to the BinaryFormatter. The type is obviously not ready 
+to be serialized by the BinaryFormatter and the exception is thrown.
+
+
+Expected Results:
+No exceptions should be thrown. The ObjectStateFormatter should try to 
+use an associated type converter BEFORE using the BinaryFormatter.
+
+How often does this happen? 
+Always
