Entity Framework Code First Conventions Type Discovery
Example
By default Code First includes in model
- Types defined as a DbSet property in context class.
- Reference types included in entity types even if they are defined in different assembly.
- Derived classes even if only the base class is defined as DbSet property
Here is an example, that we are only adding Company as DbSet<Company> in our context class:
public class Company
{
public int Id { set; get; }
public string Name { set; get; }
public virtual ICollection<Department> Departments { set; get; }
}
public class Department
{
public int Id { set; get; }
public string Name { set; get; }
public virtual ICollection<Person> Staff { set; get; }
}
[Table("Staff")]
public class Person
{
public int Id { set; get; }
public string Name { set; get; }
public decimal Salary { set; get; }
}
public class ProjectManager : Person
{
public string ProjectManagerProperty { set; get; }
}
public class Developer : Person
{
public string DeveloperProperty { set; get; }
}
public class Tester : Person
{
public string TesterProperty { set; get; }
}
public class ApplicationDbContext : DbContext
{
public DbSet<Company> Companies { set; get; }
}
We can see that all the classes are included in model
