How to handle system shutdown event using Avalonia framework on both Windows and Linux systems?

I'm developing an application using C# with Avalonia framework. When system shuts down I need to perform some tasks (write logs and metadata to files) for application to complete job gracefully. Previously using WPF on Windows I used subscription to Microsoft.Win32.SystemEvents.SessionEnding event. But as namespace says, it is OS dependent. In Avalonia I tried to handle AppDomain.CurrentDomain.ProcessExit or ((IClassicDesktopStyleApplicationLifetime)ApplicationLifetime).Exit events but neither of them fired. So, question is, what is the correct way to handle OS shutdown on both systems.

Solution

  • You should try the shutdown event, it's signature is as follows...

    ((IClassicDesktopStyleApplicationLifetime)ApplicationLifetime).ShutdownRequested += delegate(object? sender, ShutdownRequestedEventArgs e) 
{
    //Write logs and metadata to files here...
};
