public string ID { get; set; }
public string ContinentID { get; set; }
public string Name { get; set; }
public int? Population { get; set; }
public int? Area { get; set; }
public DateTime? UnitedNationsDate { get; set; }
public Continent Continent { get; set; }
}Entity Framework uses C# classes to define the database model. This is an in-memory representation of data stored in a database table. Several model classes combine to form the schema for the database.
Each property maps to a column in a database table. The bottom line in the example shows a type of Continent which implies a relationship to another table.
