 # Create a simple data application with WPF and Entity Framework 6
 
-This walkthrough shows how to create a basic "forms over data" application in Visual Studio. The app uses SQL Server LocalDB, the Northwind database, Entity Framework 6, and Windows Presentation Foundation for .NET Framework. It shows how to do basic databinding with a master-detail view, and it also has a custom Binding Navigator with buttons for **Move Next**, **Move Previous**, **Move to beginning**, **Move to end**, **Update** and **Delete**.

 This article focuses on using data tools in Visual Studio, and does not attempt to explain the underlying technologies in any depth. It assumes that you have a basic familiarity with XAML, Entity Framework, and SQL. This example also does not demonstrate Model-View-ViewModel (MVVM) architecture, which is standard for WPF applications. However, you can copy this code into your own MVVM application with few modifications.
 
-> [!NOTE]
-> This article has not been updated for .NET Core and Entity Framework Core.

 ## Install and connect to Northwind
 
 This example uses SQL Server Express LocalDB and the Northwind sample database. If the ADO.NET data provider for that product supports Entity Framework, it should work with other SQL database products just as well.
