Using Entity Framework Core with ASP.NET Core

Entity Framework Core 2.0 is included with ASP.NET Core 2.0, so it is a natural way to get real data into a website.

Creating Entity models for Northwind

Creating entity data models in separate class libraries that are .NET Standard 2.0-compatible so that they can be reused in other types of projects is good practice.

Creating a class library for the Northwind entity classes

In Visual Studio 2017, choose File | Add | New Project....

In the Add New Project dialog, in the Installed list, expand Visual C#, and select .NET Standard. In the center list, select Class Library (.NET Standard), type the name as NorthwindEntitiesLib, type the location as C:\Code\Part3, and then click on OK, as shown in the following screenshot:

In Visual Studio Code, in the Part3 folder, create a folder named NorthwindEntitiesLib, and open it with Visual Studio Code.

In the Integrated Terminal, enter the command: dotnet new classlib.

In Visual Studio Code, open the Part3 folder...
