[Mono-list] Fixing 2.4.2p2 NotImplementedException

[Andrus Moor]

In Mono  2.4.2p2  method

private object NormalizeDbType(object value)
{
  System.Data.Linq.Binary b = value as System.Data.Linq.Binary;
  if (b != null)
                return b.ToArray();
   return value;
  }

causes NotImplementedException

How to fix this in stable release of Mono? Is it possible to change this 
code so that it works ?

Andrus.
