Question

我正在开发一个或多或少的vanilla WPF应用程序。我在我的解决方案中添加了一个Windows安装项目，并从我的WPF应用程序中添加了项目输出。

运行安装程序之后，我无法运行该软件（虽然它在Visual Studio 2010中运行良好。）只有一个短暂的等待期，然后应用程序会安静地退出。 Windows事件日志中出现以下错误。我对WPF开发还不熟悉......不知道我在这里缺少什么吗？

感谢您的帮助！

编辑：根据请求从App.xaml提供xaml代码。

<Application x:Class="MyApp.App"

您需要处理App类的DispatcherUnhandledException事件，并且不仅要写入传递给eventhandler的异常的Message和StackTrace属性，还要写出其InnerException属性中的异常（遵循嵌套异常，直到InnerException为null）。写入日志文件，以便在应用程序关闭后进行检查。通常只会有一个内部异常指出无法解析XAML的原因。
