Error in Entity Framework in code first pattern
When I try to execute the update-database command, I get the error:
Foreign key 'FK_dbo.HomeWork_dbo.Students_StudentID' references invalid column 'ID' in referenced table 'dbo.Students'.
This is my homework class inherited by the parent class containing a few properties, like ID, etc.
public class HomeWork: Commons_Parent
public DateTime DateCreated get; set;
public string Content get; set;
public string Grade get; set;
public int StudentID get; set;
public Student Student get; set;
This is my Student class inherited by the class Person which hold properties like Name, etc.
public class Student: Person
public DateTime DateOfBirth get; set;
public Class Std_Class get; set;
public int Class_ID get; set;
public List<Parent> Parents get; set;
