Exception information (cannot be converted to type)

When migrating or working with existing data model it could be nice to have more about exceptions that is throwing for debug purpose...

Perhaps just me, but if could have little more information about the enitity in this message I could help faster to resolve the problem.

System.ArgumentException was unhandled
  Message="Object of type 'System.DateTime' cannot be converted to type 'System.Nullable`1[System.Int64]'."

We usually try to indicate which field is having the problem when we hit this kind of error, but it looks like this case slipped through the net.  I've logged a bug and will look into it.  Thanks!

 If you can put the field in the message it will help much :-)
