Entity Framework Not Recognizing Foreign Key?

I'm trying to set a variable like so...

var userID = WebMatrix.WebData.WebSecurity.CurrentUserId;
var options = db.UserProfiles.Find(userID).TaskTypeSetting;

I'm using the user authentication table provided by the basic Internet Application template.

Row UserId in table UserProfile has a one-to-many relationship with row User in table TaskTypeSetting.

It is telling me that it cannot find a definition for TaskTypeSetting. Shouldn't I be able to do this if my relationships are set up properly?

Here is the model for the table:

namespace DailyTaskList.Models
{
    using System;
    using System.Collections.Generic;

    public partial class TaskTypeSetting
    {
        public int ID { get; set; }
        public int Type { get; set; }
        public int User { get; set; }
    }
}

It looks like it's not adding the relationship to the code? The .edmx diagram shows the relationships as I have them set up.

Edit:

UserProfile class definition:

namespace DailyTaskList.Models
{
    using System;
    using System.Collections.Generic;

    public partial class UserProfile
    {
        public int UserId { get; set; }
        public string UserName { get; set; }
    }
}

Compiler Error Message: CS1061: 'DailyTaskList.Models.UserProfile' does not contain a definition for 'TaskSetting' and no extension method 'TaskSetting' accepting a first argument of type 'DailyTaskList.Models.UserProfile' could be found (are you missing a using directive or an assembly reference?)

I'm also getting this under Mapping Details:

Mappings are not allowed for an association over exposed foreign keys.
