UWP和无头应用程序中未处理的异常

Question

I've read a lot about catching unhandled exception in an UWP app. All suggest tu use AppDomain.UnhandledException. But what to do in a headless application, there is no AppDomain and also no UI-thread.

My app starts several threads, binds to several udp/tcp listeners and makes HTTP requests that may crash. I want to log theses crashes to stabilize the app.

未处理的异常检测封装在Application中 ，该应用程序通常在App.xaml的初始XAML中提供，因此无头应用无法检测到未处理的异常。有一个非常简单的执行模型，并且没有进程边界。如果要在无头应用程序中捕获异常，则应在每个线程中添加try / catch。您可以参考此处以获取更多信息。
