I am getting a null reference exception, but I can't figure out what is going on.  The below is the stack trace.  In the Debug Windows, it shows that the Property "LastSynchronized" is being set.    The below line is what is shown in the Debug Windows, from the IB.Designer.cs file.  But neither "this" nor "Value" is null.
 

set { PropertyMetadata.LastSynchronized.SetValue(this, value); }

Never mind, I got this resolved.  It seems that it was not properly added to a EntityManager.  After call EntityManager.AddEntity(), it no longer gave this error.
