Version 1.3.0 fails with System.PlatformNotSupportedException on Windows

[nefarius]

Hey hey,

so I updated from 1.2.0 to 1.3.0 today and the same unchanged code now fails with

System.PlatformNotSupportedException 
Operation is not supported on this platform.
   at DesktopNotifications.Windows.WindowsNotificationManager..ctor(WindowsApplicationContext context)

My code:

public partial class App : Application
{
    private readonly IHost _host;

    public App()
    {
        _host = Host.CreateDefaultBuilder()
            .ConfigureServices((hostContext, services) =>
            {
                services.AddSingleton<INotificationManager, WindowsNotificationManager>();

                services.AddHostedService<UpdateMessageSubscriber>();
            }).Build();
    }

    private async void App_OnStartup(object sender, StartupEventArgs e)
    {
        // throws exception now
        INotificationManager notificationManager = _host.Services.GetRequiredService<INotificationManager>();

        await notificationManager.Initialize();

        await _host.StartAsync();
    }
}

Thank you!

Which platform are you running on?

Oh I know why this is happening. I am creating nugets on the CI, but only under ubuntu environment. So the windows package will be broken since it uses the "null impl". Will fix.

Which platform are you running on?

To answer your question, happens on both Windows 10 and 11.

@nefarius I rebuilt the packages locally and pushed v1.3.1 to nuget. Make sure to target either net6.0-windows10.0.17763.0 or n etcoreapp3.1 in your application. It doesn't wotk with net6.0 unfortunately due to the windows-specific TFM used internally. I will add a note about that in the readme.

Now it seems to work on Windows (using 1.3.1) but fails to compile on Linux again (with net6.0 target). Honestly multi-target and multi-OS stuff with .NET is pure horror.

The error is gone now, thank you! Now I need to figure out why I am not getting any notifications whatsoever on Windows 11, but I haven't yet pinned down that issue to something with the library or not.

Are you seeing the application in the windows Start menu?

Are you seeing the application in the windows Start menu?

Good point, I'll get back to you on this tomorrow.

Are you seeing the application in the windows Start menu?

Yep, it's there!

Did a few more tests, nothing is appearing on Windows 11 22H2, no exceptions, nothing in Event Viewer... 🤔

NVM just tried it in a fresh Windows 11 VM and there it works as expected, must be something wrong with the particular test machine, closing, thanks!
