title: Default IValueConverter
body: <p>I have a simple <code>IValueConverter</code> which just uses a <code>TypeConverter</code> to do the conversions. However there are some cases where the <code>TypeConverter</code> provided will fail.</p>
  
  <p>I would like to fall back to whatever WPF would have used if the the <code>Binding</code> was not provided with a converter. Using reflector I have determined that there is a <code>DefaultValueConverter</code> however it is internal to <code>MS.Internal.Data</code>. </p>
  
  <p>Is there a simple way I can get my hands on a <code>DefaultValueConverter</code> or something that does the same thing?</p>
