Usage

Add to your App constructors:

public sealed partial class App
{
    private InteractionManager InteractionManager { get; } = new();

    public App()
    {
        InteractionManager.Register();

        // Not necessary. Displays unhandled exceptions using MessageInteractions.Exception.
        // InteractionManager.CatchUnhandledExceptions();

        // your code
    }
}

FileInteractions

var data = await FileInteractions.OpenFile.Handle(new OpenFileArguments
{
    SuggestedFileName = "my.txt",
    Extensions = new[] { ".txt" },
    FilterName = "My txt files",
});
var text = data.Text;

var fileName = await FileInteractions.SaveFile.Handle(new SaveFileArguments
{
    SuggestedFileName = "my.txt",
    Extension = ".txt",
    FilterName = "My txt files",
    BytesFunc = () => Task.FromResult(Encoding.UTF8.GetBytes(text)),
});

MessageInteractions

WinUI requires a window to display the ContentDialog, so you'll need to set it explicitly in your App.OnLaunched:

    protected override void OnLaunched(LaunchActivatedEventArgs args)
    {
#if HAS_WINUI
        var window = new Window();
        MessageInteractionManager.Window = window;
#endif
    }
