Good example of combining WPF + WCF + Entity Framework [closed]

Have you looked at the walk through below which just include WPF + WCF + Entity Framework only:

http://msdn.microsoft.com/en-us/library/dd465161.aspx

In this walkthrough, you will create a WPF application that contains data-bound controls. The controls are bound to customer records that are encapsulated in a WCF Data Service. You will also add buttons that customers can use to view and update records.

This walkthrough illustrates the following tasks:

1. Creating an Entity Data Model that is generated from data in the AdventureWorksLT sample database.
2. Creating a WCF Data Service that exposes the data in the Entity Data Model to a WPF application.
3. Creating a set of data-bound controls by dragging items from the Data Sources window to the WPF designer.
4. Creating buttons that navigate forward and backward through customer records.
5. Creating a button that saves changes to data in the controls to the WCF Data Service and the underlying data source.

Demonstrates WPF, MVVM, WCF, WF and Entity Framework 6.0 maybe a good demo for you. and there are other Layered Architecture Samples.

I have done some digging and this is what I've found:

Karl Shifflett's Netflix Stuff Application(WPF, MVVM, Data Services)

IssueVision(Silverlight, MVVM, WCF RIA Services, Entity Data Model)
