Xamarin Forms ListView not showing TextCells
<p>Here is the code I am working with right now...</p>

<pre><code>items = new List&lt;TextCell&gt;();
        items.Add(new TextCell { Text = "Cake", TextColor = Color.Green, Detail = "12 hours left!", DetailColor = Color.Black});
        items.Add(new TextCell { Text = "Pie", TextColor = Color.Green, Detail = "14 hours left!", DetailColor = Color.Black });


        var buy = new ContentPage
        {
            Title = "Buy",
            Content = new StackLayout
            {
                VerticalOptions = LayoutOptions.Center,
                Children = {
                    new ListView
                    {
                       ItemsSource = items,
                       ItemTemplate = new DataTemplate(typeof(TextCell))
                    }
                }
            }
        };
</code></pre>

<p>The ListView is populated with two blank views with no content.</p>

<p>Am I missing some property?</p>
