Microsoft’s ADO.NET Entity Framework, known widely as EF, introduced out-of-thebox
Object Relational Mapping to .NET and Visual Studio. Central to Entity Framework
was the Entity Data Model, a conceptual model of your application domain that
maps back to the schema of your database. This conceptual model describes the core
classes in your application. Entity Framework uses this conceptual model while querying
from the database, creating objects from that data and then persisting changes back
to the database....

WPF Data Binding
This section discusses binding with Windows Presentation Foundation (WPF). In this example, you focus on the sales side of things, pulling in SalesOrderHeader and SalesOrderDetail information to populate a simple WPF form.
