棱镜6.2绑定到模型不ViewModel

我想在C＃中使用Prism，但我似乎已经设置它，以便它绑定到我的模型中的项目，而不是我的viewmodel。这是一个简短的程序，更多的是一个学习工具，任何东西。当我将项目移动到ViewModel时，SetProperty似乎没有通知更改的视图。棱镜6.2绑定到模型不ViewModel

有关我如何反向安装的任何想法？

型号：

namespace XMLValueModifier_Threaded_WPF.Models 
{ 
    public class XMLReadFileModel : BindableBase 
    { 
     private string _XMLMasterFile2 = "0"; 

     public string XMLGetFileName() 
     { 
      if (_XMLMasterFile2 != "1") 
       { 
        Microsoft.Win32.OpenFileDialog _XMLMasterFileDialog = new Microsoft.Win32.OpenFileDialog(); 

        _XMLMasterFileDialog.DefaultExt = "xml"; 
        _XMLMasterFileDialog.Filter = "xml Files (*.xml; *.XML) | *.xml; *.XML"; 

        Nullable<bool> result = _XMLMasterFileDialog.ShowDialog(); 

        if (result == true) 
        { 
         return _XMLMasterFileDialog.FileName; 
        } 
        return ""; 
       } 
       else 
       { 
        return ""; 
       } 
     } 
    } 
}

视图模型：

namespace XMLValueModifier_Threaded_WPF.ViewModels 
{ 
    public class MainDialogueViewModel : BindableBase 
    { 
     private string _XMLMasterFile; 

     public ICommand MasterFileLocation 
     { 
      get; 
      set; 
     } 

     public ICommand XMLFileLocation 
     { 
      get; 
      set; 
     } 

     public string XMLMasterFile 
     { 
      get 
      { 
       return _XMLMasterFile; 
      } 
      set 
      { 

       SetProperty(ref _XMLMasterFile, value); 
      } 
     } 

     private XMLReadFileModel xmlReadFileModel = new XMLReadFileModel(); 
     public MainDialogueViewModel() 
     { 
      XMLReadFileModel xmlReadFileModel = new XMLReadFileModel(); 
      Message = "example message"; 
      XMLMasterFile = "example File"; 

      this.MasterFileLocation = new DelegateCommand(chooseFile, canChooseFile); 
      this.XMLFileLocation = new DelegateCommand(chooseFile, canChooseFile); 
     } 

     public void masterfilelocation() 
     { 
      MessageBox.Show("i am here"); 
      return; 
     } 

     private void chooseFile() 
     { 
      XMLMasterFile = xmlReadFileModel.XMLGetFileName(); 
     } 

     private bool canChooseFile() 
     { 
      if (XMLMasterFile != null) 
      { 
       return true; 
      } 
      else 
      { 
       return true; 
      } 
     } 

    } 
}

XAML：

<Window x:Class="XMLValueModifier_Threaded_WPF.Views.MainDialogue" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
