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 System.Windows; 7 using Microsoft.Practices.Unity; 8 using Prism.Unity; 9 using ViewInjection.Views;10 11 namespace ViewInjection12 {13     public 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TextA.xaml。

      ();27             IRegion region = _regionManager.Regions["ContentRegion"];28             region.Add(view);29         }30     }31 }

　　5、修改App.xaml

1 using System; 2 using System.Collections.Generic; 3 using System.Configuration; 4 using System.Data; 5 using System.Linq; 6 using System.Threading.Tasks; 7 using System.Windows; 8  9 namespace ViewInjection10 {11     /// 
12     /// App.xaml 的交互逻辑13     /// 
14     public partial class App : Application15     {16         protected override void OnStartup(StartupEventArgs e)17         {18             base.OnStartup(e);19 20             var bootstrapper=new Bootstrapper();21             bootstrapper.Run();22         }23         24     }25 }
