为什么我的应用程序在启动时在System.Windows.ni.dll中崩溃而没有有用的堆栈跟踪？ （看似采用Caliburn.Micro之后）

Question

1. 从默认的“空”Windows Phone应用程序项目（Windows Phone 8）开始。我们称之为BlackAdder以获得乐趣。
2. 从Nuget添加Caliburn.Micro
3. 将MainPage.xaml移至Views子目录，并在ViewModels\MainPageViewModel.cs
中创建匹配的ViewModel
4. 在MainPage和Blackadder.Views文件中将.xaml的命名空间修复为.xaml.cs

5. 更新App.xaml

   <Application
   x:Class="BlackAdder.App"
   xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
   xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
   xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
   xmlns:local="clr-namespace:BlackAdder">
   
   <Application.Resources>
       <local:Bootstrapper x:Key="bootstrapper"/>
   </Application.Resources>
   
   </Application>
   

6. 更新App.xaml.cs

   public partial class App : Application
   {        
       public static PhoneApplicationFrame RootFrame { get; private set; }
   
       public App()
       {
         InitializeComponent();
   
        // Show graphics profiling information while debugging.
         if (Debugger.IsAttached)
         {
             ...
         }
      }
   }
   

7. 创建Bootstrapper.cs

   public class Bootstrapper : PhoneBootstrapper
   {
     private PhoneContainer container;
   
     protected override void Configure()
     {
       container = new PhoneContainer();
   
       container.RegisterPhoneServices(RootFrame);
       container.PerRequest<MainPageViewModel>();
   
       AddCustomConventions();
     }
   
     protected static void AddCustomConventions()
     {
     }
   
     protected override object GetInstance(Type service, string key)
     {
       return container.GetInstance(service, key);
     }
   
     protected override IEnumerable<object> GetAllInstances(Type service)
     {
       return container.GetAllInstances(service);
     }
   
     protected override void BuildUp(object instance)
     {
       container.BuildUp(instance);
     }
   }
   

当我们运行应用程序时，它会在一个非常奇怪的地方崩溃。

An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in System.Windows.ni.dll

Additional information: Exception has been thrown by the target of an invocation.

没有内部异常，堆栈跟踪（看似）无用。

System.Windows.ni.dll!System.Windows.Threading.DispatcherOperation.Invoke() System.Windows.ni.dll!System.Windows.Threading.Dispatcher.Dispatch(System.Windows.Threading.DispatcherPriority priority) System.Windows.ni.dll!System.Windows.Threading.Dispatcher.OnInvoke(object context) System.Windows.ni.dll!System.Windows.Hosting.CallbackCookie.Invoke(object[] args) System.Windows.RuntimeHost.ni.dll!System.Windows.RuntimeHost.ManagedHost.InvokeDelegate(System.IntPtr pHandle, int nParamCount, System.Windows.Hosting.NativeMethods.ScriptParam* pParams, System.Windows.Hosting.NativeMethods.ScriptParam* pResult)

Answer 1

事实证明这与caliburn.micro完全无关。问题在于Properties\WMAppManifest.xaml。

将MainPage.xaml移至Views子目录后，Navigation Page设置（在第一个标签Application UI上找到）需要更新为Views\MainPage.xaml < / p>
