Entity Framework Code First Conventions Relationship Convention
Example
Code First infer the relationship between the two entities using navigation property. This navigation property can be a simple reference type or collection type. For example, we defined Standard navigation property in Student class and ICollection navigation property in Standard class. So, Code First automatically created one-to-many relationship between Standards and Students DB table by inserting Standard_StandardId foreign key column in the Students table.
public class Student
{
public int StudentID { get; set; }
public string StudentName { get; set; }
public DateTime DateOfBirth { get; set; }
//Navigation property
public Standard Standard { get; set; }
}
public class Standard
{
public int StandardId { get; set; }
public string StandardName { get; set; }
//Collection navigation property
public IList<Student> Students { get; set; }
}
The above entities created the following relationship using Standard_StandardId foreign key.
