Attribute Routing Fail in Web API 2

Why does the third route fail in my Web API ?

    public class StudentCourseController : ApiController
    {
        // GET api/student
        public IEnumerable<StudentCourse> Get()
        {
            return StudentCourseRepository.GetAll();
        }

        // GET api/student/5
        public StudentCourse Get(int id)
        {
            return StudentCourseRepository.GetAll().FirstOrDefault(s => s.Id == id);
        }


        [Route("StudentAuto/{key}")]  // Does not work
        public IEnumerable<Student> StudentAuto(string key)
        {
            return StudentRepository.GetStudentsAuto(key);
        }

When i request http://localhost:5198/api/StudentCourse/StudentAuto/mi I get a 404 error.

The detail error shows

Requested URL      http://localhost:5198/api/StudentCourse/StudentAuto/mi
Physical Path      C:\Users\deb\Desktop\StudentKO\KnockoutMVC\KnockoutMVC\api\StudentCourse\StudentAuto\mi
Logon Method       Anonymous
Logon User     Anonymous

Did i miss anything ?

thanks

Attribute routing on a method does not work in conjunction with the route constraints for the controller you put into your startup, e.g. "/api/{controller}".

Therefore your [Route("StudentAuto/{key}")] route literally maps to "/StudentAuto/{key}", not "/api/StudentCourse/StudentAuto/{key}".

You can get this to work as you want by adding a [RoutePrefix] (see msdn) to your controller:

[RoutePrefix("api/StudentCourse")]
public class StudentCourseController : ApiController
{
}

Alternatively just set the whole path in your Route attribute:

[Route("api/StudentCourse/StudentAuto/{key}")]
public IEnumerable<Student> StudentAuto(string key)
{
    return StudentRepository.GetStudentsAuto(key);
}
