An entity class represents the structure of a table, and an instance of the class represents a row in that table.

Ways to define a model

First, we will review the three ways to define a model, with code examples, and then we will create some classes that implement those techniques.

Using EF Core conventions to define the model

The code we will write will use the following conventions:

• The name of a table is assumed to match the name of a DbSet property in the DbContext ...
