Where is "OrderShipper" ?

UsingCsla4-03-DataAccess.pdf refers to an OrderShipper class (page 151)  in Library.Net project in the EncapsulatedInvoke solution.

I have Csla versions going back to 4.0, but cannot seem to find the OrderShipper anywhere. I also cannot find the EncapsulatedInvoke.sln anywhere.   The only Library.Net project I have come across is in the PagedList.sln.  The Library.Net project in that has nothing called "OrderShipper".

I am looking for an example of DataPortal.BeginExecute.  I would appreciate some help.  Thanks.
