Trying to build a Windows 8 App using C# and XAML.

I've created a class:

class Tile
{
    public Tile(int ID, string Name, double Frequency, double Divider, int Value, int Turns, int StartLevel)
    {
        this.ID = ID;
        this.Name = Name;
        this.Frequency = Frequency;
        this.Divider = Divider;
        this.Value = Value;
        this.Turns = Turns;
        this.StartLevel = StartLevel;
    }

    private int ID { get; set; }
    private string Name { get; set; }
    private double Frequency { get; set; }
    private double Divider { get; set; }
    private int Value { get; set; }
    private int Turns { get; set; }
    private int StartLevel { get; set; }
}

I've added objects to a list:

List<Tile> tList = new List<Tile>();

tList.Add(new Tile(0, "Example1", 0.08, 1.00, 0, 7, 1));
tList.Add(new Tile(1, "Example2", 0.21, 1.25, 0, 0, 1));

When using standard C#, I'm able to access the properties of an object like such:

foreach (Tile t in tList)
{
    int test = t.ID;
}

The Problem: In my foreach statement above, when I type "t." all that comes up in this list of available elements is:

Equals GetHashCode GetType ToString

I Expect: The following elements to appear:

ID Name Frequency Divider Value Turns StartLevel

What am I missing here?
