Question

I get a 404 not found when I try to DELETE from my service, on the client side I use this:

On my Service side I use this:

    [OperationContract]
    [WebInvoke(Method = "DELETE", BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "/Student")]
    void removeStudent(Student studentID);

    List<Student> students = new List<Student>();
    public void removeStudent(Student studentID)
    {
        students.Remove(students.Find(f => f.StudentID.Equals(studentID)));
    }

Answer 1

Based on what i see above, you are passing the some text to the URL on the client side BUT expecting a Student object which doesn’t seem right.

I think the convention is that the DELETE should have the same URI template as a GET.

  [WebInvoke(Method = "DELETE", BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "/{studentID}")]
    void removeStudent(string studentID);

or

void removeStudent(int studentID);
