>Thank you for the explanation; this is now coming back. So I suppose I need to make it a field and not a property.



You have implemented it as a field.

A property has get/set accessors http://msdn.microsoft.com/en-us/library/w86s7x04.aspx


But since it is readonly - I would just leave it as a field
