我刚刚从网站下载了后台工作人员示例以供参考，当我运行应用程序时，它运行没有任何问题。后台任务正常执行，并显示 toast 通知。

但问题是我将目标版本从 Windows Phone 7.1 更改为 Windows Phone 8 后，它没有执行后台任务。它显示错误System.Windows.pdb not loaded。

我没有更改项目中的单段代码。我不知道为什么会发生这个错误..请帮助我..

这是我从网站下载的示例。

这是调用堆栈 > System.Windows.ni.dll!MS.Internal.JoltHelper.OnUnhandledException(object sender, System.UnhandledExceptionEventArgs args) Unknown [Native to Managed Transition]

pdb 文件是一个符号文件，用于在调试时单步执行代码。

我不确定为什么在调试时要进入 system.windows ...您可能需要查看工具-> 选项并检查您是否没有尝试进入 Microsoft 代码。

问题是您遇到了异常，而调试器正在尝试获取它，但它正在满足该异常。

由于您无法更改它，因此进入该程序集毫无意义-但是也许您想为此而寻找。我个人不会打扰;p
