19,337 PointsGetting a 1520 Compile error on my Teacher.cs file
I'm having trouble with this error because it says that I haven't specified the return type but when I do it says it's already specified earlier in the class. I've also checked the cases in the Courses and Course constructors and classes to make sure they match.
namespace Treehouse.CodeChallenges
{
public class Course
{
public int Id { get; set; }
public string Title { get; set; }
public string Description { get; set; }
public int Length { get; set; }
public int TeacherId { get; set; }
public Teacher Teacher { get; set; }
}
}
using System.Collections.Generic;
namespace Treehouse.CodeChallenges
{
public class Teacher
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public ICollection<Course> Courses { get; set; }
public Courses()
{
Courses = new List<Course>();
}
}
}

should be for Teacher
and not for Courses
, so instead of public Courses()
, try public Teacher()
.
