I am new to ASP.NET and trying out the new MVC 6 framework. i want to create an To do list App. After user authentication, I am redirecting to a dashboard page where I want to display to do tasks. I have created a model Task, but i am unsure about how to add a Foreign Key for the user id so that when i redirect the user to the dashboard page I can query based on the user's id.

```
public class Task
{
    public int Id { get; set; }

    // i want to add a fk to aspnetuser id here 
}

```

Thank you for your help.
