[SOLVED] How to Replace Acr.UserDialogs in a MAUI with WinUI3 Project?

How to Replace Acr.UserDialogs in a MAUI with WinUI3 Project?

I am migrating a Xamarin project with UWP to a .NET MAUI project with WinUI 3. In my Xamarin project, I used Acr.UserDialogs.IProgressDialog and Acr.UserDialogs.UserDialogs.Instance.Alert for displaying progress dialogs and alerts. Since Acr.UserDialogs does not support platforms outside of Android, iOS, and UWP, I need to find an equivalent solution in MAUI with WinUI 3.

Here is my current UWP code:

using Acr.UserDialogs;

public class ImportDataForWin : IImportDataForWin { private IProgressDialog progress;

public async Task ImportData()
{
    var picker = new Windows.Storage.Pickers.FileOpenPicker
    {
        ViewMode = Windows.Storage.Pickers.PickerViewMode.Thumbnail,
        SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.PicturesLibrary
    };

    picker.FileTypeFilter.Add(".xlsx");
    picker.FileTypeFilter.Add(".xls");

    var file = await picker.PickSingleFileAsync();

    if (file != null)
    {
        var config = new ProgressDialogConfig()
            .SetTitle("Importing Data")
            .SetIsDeterministic(false);

        progress = UserDialogs.Instance.Progress(config);
        progress.PercentComplete = 0;
        progress.Show();

        // Some code
        var countMax = itemsToAdd.Count();
        var rowCount = 0;
        foreach (var item in itemsToAdd)
        {
            rowCount++;
            await SaveData(item);
            progress.PercentComplete = (rowCount * 100) / countMax;
        }
        progress.Hide();

        UserDialogs.Instance.Alert("errorMessage");
    }
}

}

How can I achieve similar functionality in MAUI with WinUI 3?

Specifically, I need help with:

Displaying a progress dialog during the data import. Showing an alert dialog when the import is complete or if there is an error.

Any guidance or code examples would be greatly appreciated.
