This is part two of our series on Entity Framework, if you would like to catch up with what we did on on part one, feel free to go over the lesson so that you can follow along.
In the last part we installed Entity Framework 6.1.1 with NuGet package management tool in Visual Studio. In this lesson we will learn to create an Entity Model using the Northwind database. Follow the steps below.
The Northwind Entity Model is created
The Entity model context code files are also generated as well. To open the Entity Model designer screen just double click on the NorthwindModel.edmx file
If you look the Web.config file you will see it has been modified significantly with Entity Framework settings without you even opening it. It's all done for you automatically for you.
