【问题描述】:
我正在开发一个或多或少的普通 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。
运行安装程序后,我无法运行该软件(尽管它在 Visual Studio 2010 中运行良好。)只有一个短暂的等待期,然后应用程序安静地退出。 Windows 事件日志中出现以下错误。我对 WPF 开发相当陌生...知道我在这里缺少什么吗?
感谢您的帮助!
编辑:根据要求从 App.xaml 提供 xaml 代码。

【问题讨论】:
-
在这里看到一些相关代码确实有助于跟踪此类问题。
-
您需要处理
App类的DispatcherUnhandledException事件并写出Message和StackTrace属性,不仅是传递给事件处理程序的异常,还有它的InnerException属性(遵循嵌套异常,直到InnerException为空。写入日志文件,以便在应用程序关闭后进行检查。通常只有一个内部异常指出无法解析 XAML 的确切原因. -
乔尔,这完全解决了我的问题!只需要在某个地方注入诊断代码,而那个事件就是这样。原来我的安装程序缺少应用程序预期存在的文件。如果您发表评论作为答案,我会接受!
