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

// Open
var file = await FileInteractions.OpenFile.Handle(new OpenFileArguments
{
    SuggestedFileName = "my.txt",
    Extensions = new[] { ".txt" },
    FilterName = "My txt files",
});
if (file == null)
{
    return;
}
var text = await file.ReadTextAsync().ConfigureAwait(true);

// Save (you need to save file from previuos step)
await file.WriteTextAsync(text).ConfigureAwait(false);

// Save As
var file = await FileInteractions.SaveFile.Handle(new SaveFileArguments(".txt")
{
    SuggestedFileName = "my.txt",
    FilterName = "My txt files",
});
if (file == null)
{
    return;
}
await file.WriteTextAsync(text).ConfigureAwait(false);

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
}
