Sample affected

• MvvmDialogSample

Proposed solution

With the latest version of Avalonia and its dependencies (11.2.0), the file src/Avalonia.Samples/ViewInteraction/MvvmDialogSample/Views/InteractionView.axaml.cs fails to compile, returning Error CS1503.

As a workaround, downgrading the NuGet packages to version 11.1.0 resolves the issue.

@BiDuang thanks for reporting this. Indeed, there was a change in ReactiveUI that I wasn't aware of. I filed a PR to fix it, however we are checking with the team if we need to revert this change or not.

Sorry for the inconvinience.

public partial class InteractionView : ReactiveUserControl<InteractionViewModel>
{
    public InteractionView()
    {
        InitializeComponent();

        this.WhenActivated(d =>
        {
-           d(ViewModel.SelectFilesInteraction.RegisterHandler(this.InteractionHandler));
+           d(ViewModel!.SelectFilesInteraction.RegisterHandler(this.InteractionHandler));
        });
    }

-    private async Task InteractionHandler(InteractionContext<string?, string[]?> context)
+    private async Task InteractionHandler(IInteractionContext<string?, string[]?> context)
    {
        // Get our parent top level control in order to get the needed service (in our sample the storage provider. Can also be the clipboard etc.)
        var topLevel = TopLevel.GetTopLevel(this);
        var storageFiles = await topLevel!.StorageProvider
            .OpenFilePickerAsync(
                        new FilePickerOpenOptions()
                        {
                            AllowMultiple = true,
                            Title = context.Input
                        });

-        context.SetOutput(storageFiles?.Select(x => x.Name).ToArray());
+        context.SetOutput(storageFiles.Select(x => x.Name).ToArray());
    }
}
