}
public

{
if
(index > Count - 1 || index < 0)

}
List.RemoveAt(index);
}
public

(index > Count - 1 || index < 0)
{
throw
new
Exception("Index out of bounds");
}
return
(ApplicationInformation) List[index];
}
}
}
}
and it gives no errors when debugging but when it tries to open the page this error happens:
Server Error in '/APPRECWS' Application.
You must implement a default accessor on APPRECWS.AplicationRecordWS+DataResult because it inherits from ICollection.
I'm using VS2003, Can anyone help me please?
Thanks in advance
