MVC 6 - No Parameterless Constructor defined for this object

Question

I have created an MVC 6 project (MVC Movies) which has SQL tables such as AspNetUsers.

I want to be able to display a list of Users who are on the AspNetUsers table so for that I have a Model 'AspNetUsers':

public class AspNetUsers
{
    public int ID { get; set; }
    public string Email { get; set; }
}

I also then have another class 'AspNetUserInfo' which holds a List of AspNetUsers:

public class AspNetUserInfo
{
    public List<AspNetUsers> MyUserList { get; set; }
}

To show this list I then need a Controller with Views, and this is where my issue Starts: Everytime I try to create Views I am met with this:

I can create a Controller (without views) and I have done:

    public IActionResult Index()
    {
        AspNetUserInfo userInfo = new Models.AspNetUserInfo();
        List<AspNetUsers> aspUsers = userInfo.MyUserList.ToList();
        return View(aspUsers);
    }

I cannot create a Controller with views nor can I create views for this controller without seeing the error above. I think that I need to add a Parameterless Constructor in my ApplicationDbContext but I am unsure how to do this.

Thanks in advance for any help.

ActionInvoker is the component that invokes the action in the controller. I think this might mean your controller doesn't have an empty constructor? — Brian Mains, Sep 20 '16 at 12:40
Hi James please refer the below stackoverflow post http://stackoverflow.com/questions/1355464/asp-net-mvc-no-parameterless-constructor-defined-for-this-object — Chandru velan, Sep 20 '16 at 12:41
@Chandruvelan Thanks I'll take a look and hopefully understand it — James Tordoff, Sep 20 '16 at 12:54
It complains about the dbcontext, can you show the constructor(s) for your controller? — Lasse V. Karlsen, Sep 20 '16 at 13:31
@SunilKumar I think that my AspNetUserInfo class relies on AspNetUser class to create the list if that is what you mean? — James Tordoff, Sep 20 '16 at 13:42
Answer is probably no empty constructor on your controller but also if you have an AspNetUsers table I assume you are using Identity Framework so why are you creating these classes instead of using framework? — Paul Swetz, Sep 20 '16 at 13:43
