Recycle bin is not available on this platform

Error message

Recycle bin is not available on this platform

What it means

ExecuteCurrentDeleteOperationAsync in ConfirmDeleteDialogViewModel performs a recycle-bin delete when IsPermanentDelete is false. Before calling NativeFileOperations.RecycleBin.MoveFilesToRecycleBinAsync it checks NativeFileOperations.IsRecycleBinAvailable and throws NotSupportedException when the current platform has no recycle-bin support. This prevents pretending a soft delete happened on platforms where it cannot.

Solutions

1. Choose 'Delete permanently' in the delete dialog on platforms without recycle-bin support
2. Update NativeFileOperations/recycle-bin backend to support the target platform (e.g. freedesktop Trash on Linux)
3. In UI code, disable/hide the recycle-bin option when IsRecycleBinAvailable is false so the user never reaches this path
4. Catch NotSupportedException and fall back to a permanent delete with a confirmation prompt

Example fix

// before
if (!NativeFileOperations.IsRecycleBinAvailable)
    throw new NotSupportedException("Recycle bin is not available on this platform");

// after
if (!NativeFileOperations.IsRecycleBinAvailable)
{
    Logger.Warn("Recycle bin unavailable; falling back to permanent delete");
    await DeletePermanentlyAsync(paths);
    return;
}

// Before showing the delete dialog
if (!NativeFileOperations.IsRecycleBinAvailable)
{
    confirmDeleteVm.IsPermanentDelete = true; // force permanent delete on unsupported platforms
}

bool CanRecycle() => NativeFileOperations.IsRecycleBinAvailable;

try
{
    await confirmDeleteVm.ExecuteCurrentDeleteOperationAsync();
}
catch (NotSupportedException ex) when (ex.Message.Contains("Recycle bin"))
{
    Logger.Warn(ex, "Recycle bin unavailable; prompting for permanent delete");
    await ShowPermanentDeleteFallbackDialogAsync();
}

When it happens

Trigger: Running the confirm-delete dialog with 'move to recycle bin' selected on a platform where NativeFileOperations.IsRecycleBinAvailable is false (e.g. Linux or macOS without a recycle-bin implementation).

Common situations: Users on Linux deleting models/images with the default non-permanent delete option; CI/headless environments without a desktop trash service; platform-specific builds lacking the native recycle-bin backend.
