LINQ To SQL DataService Plus WPF Databinding of that service needed

What I need are 2 projects completed plus a [login to view URL] file The first project needed is a data service project (using the northwind database and using LINQ To SQL). The second project is a WPF application that will use the service. The WPF Application needs to have databinding as well in addition to validation. They need to be programmed in Visual Basic (using the .net framework 3.5 service pack 1). The connection string needs to be in the [login to view URL] file (so I can change to my connection to the northwind database). The project should show about 3 tables being used. The purpose of this project is for me to learn databinding and wcf web services (dataservices). Needs web service instead of just using the LINQ To SQL class on the WPF application because the target machine for the WPF will only have access to the database through the web service (which would be hosted through IIS). ## Deliverables The full source code for the 2 projects. The validation needs to somehow be done differently than just simply code like this if CustomerText.Text="" then msgbox "Needs to enter customer name" end if Also a [login to view URL] to show the steps required for setting up the service plus setting up the databinding through WPF. The [login to view URL] does not need to show how to set a service reference since I know how to do that. The data service must use LINQ To SQL; not Entities one. ## Platform Windows XP Home Edition.
