Caliburn Micro - TextBox 中的文本不会显示

Question

我正在学习旧的 Caliburn Micro 教程 (here). I am up to part 2 (here)。我已设法更新 App.xaml 和 AppBootstrapper.cs 以与 3.0.3 和 WPF 兼容（如此处 'Documentation' 页面上的 'WPF' 部分所述）。我正在使用 VS 2013。

本教程显示初始化后出现值“50”的应用程序。我的应用只显示了这个：

目前的代码如下：

App.xaml

<Application
xmlns:local="clr-namespace:CaliburnMicroApp"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class=" CaliburnMicroApp.App">
<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary>
                <local:AppBootstrapper x:Key="bootstrapper" />
            </ResourceDictionary>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

AppViewModel.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Caliburn.Micro;

namespace CaliburnMicroApp.ViewModels
{
    class AppViewModel : PropertyChangedBase
    {
        private int _count = 50;

        private int Count
        {
            get { return _count; }
            set
            {
                _count = value;
                NotifyOfPropertyChange(() => Count);
                NotifyOfPropertyChange(() => CanIncrementCount);
            }
        }

        public void IncrementCount()
        {
            Count++;
        }

        public bool CanIncrementCount
        {
            get { return Count < 100; }
        }
    }
}

AppView.xaml

<UserControl x:Class="CaliburnMicroApp.Views.AppView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006">
    <Grid Width="300" Height="300" Background="LightBlue">
        <RepeatButton Name="IncrementCount" Content="Up" Margin="15" VerticalAlignment="Top" />
        <TextBlock Name="Count" Margin="20" FontSize="150" VerticalAlignment="Center" HorizontalAlignment="Center" />
    </Grid>
</UserControl>

AppBootstrapper.cs

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Caliburn.Micro;
using CaliburnMicroApp.ViewModels;
using System.Windows;


namespace CaliburnMicroApp
{
    public class AppBootstrapper : Caliburn.Micro.BootstrapperBase
    {
        public AppBootstrapper()
        {
            Initialize();
        }

        protected override void OnStartup(object sender, StartupEventArgs e)
        {
            DisplayRootViewFor<AppViewModel>();
        }
    }
}
