.NET Core 没有任何关于未处理异常的消息

Question

Trying to migrate app from .NET Framework to .NET (Core) 5.0, my task is made harder by the fact that whenever there's an unhandled exception in the .NET 5 app, I get no error message, no "Application error" event log, no nothing: The app just stops.

This contrasts the .NET Framework 4.8 app I tried on the same machine, which outputs the unhandled exception and adds an "Application Error" entry to the event log.

Is that normal, or is my .NET 5 installation broken somehow?

There are Exception Handler Events on ApplicationDomain that you can try;

• AppDomain.CurrentDomain.UnhandledException += UnhandledHandler
• AppDomain.CurrentDomain.FirstChanceException += FirstChanceHandler

Debug with this Events to observe errors, you should define at the beggining of the "Main" method in Program.cs
