I have following layers in my applicaiton
Date Layer (reference to Model)
Business Layer(reference to Model ,Data)
Model
Service(WCF)-(reference to Model,Business Layer)
UI (WPF/Silver Light) - Connected via WCF service
How do i detect the changed poco entities in an ObservableCollection in UI layer?
for sending it back to server from client side for saving ? instead of sending all data back to sever side(via WCF)?
or
how to perform add/delete/update operation on entities in the collection in UI layer?
I am using
VS2010/2012
C#
EF 5
ADO.NET POCOEntityGenerator With WCF Support(for generating .tt templates from Model.edmx)
SQL Server 2012
Even though searched a lot of places I didn't find a proper solution..
please help if any ideas...
Thanks...
