1、将App.xaml中的StartupUri="MainWindow.xaml"删除。

　　2、使用NuGet安装Prism.Wpf、Prism.Core、Prism.Unity。

　　3、添加类“Bootstrapper”，编辑如下：

1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 6 using Microsoft.Practices.Unity; 7 using System.Windows; 8 using Prism.Unity; 9 using ViewDiscovery.Views;10 11 namespace ViewDiscovery12 {13     class Bootstrapper:UnityBootstrapper14     {15         protected override DependencyObject CreateShell()16         {17             return Container.Resolve
     
      ();18         }19 20         protected override void InitializeShell()21         {22             Application.Current.MainWindow.Show();23         }24     }25 }
     

　　4、创建文件夹Views，将MainWindow.xaml移动到此文件夹中。向Views文件夹中添加ViewA.xaml。
