title: How to convert Typed DataSet Scheme when one of the types was changed?
body: <p>I got a typed (not connected) dataset, and many records (binary seriliazed) created with this dataset.
  I've added a property to one of the types, and I want to convert the old records with the new data set.
  I know how to load them: providing custom binder for the BinaryFormatter with the old schema dll. 
  The question is how can I convert objects of the old type to objects of the new type - both types has the same name but the new one has one more property.</p>
