How to Update Lemon.ModuleNavigation.Avaloniaui" Version="2.0.3-beta"

[lixiaoxiang1369]

请问NavigationContext = navigationContext中的 navigationContext使用什么方法得到，谢谢。
public MainViewModel(IEnumerable modules,
IServiceProvider serviceProvider,
NavigationService navigationService,
IDialogService dialogService,
IRegionManager regionManager,
ILogger logger)
{
_logger = logger;
_navigationService = navigationService;
_serviceProvider = serviceProvider;
_dialogService = dialogService;
_regionManager = regionManager;

 _navigationService = navigationService;
 NavigationContext = navigationContext;
 Modules = new ObservableCollection<IModule>(modules);
 //foreach (IModule module in Modules)
 //{
 //    module.Initialize();
 //}
 SelectedModule = Modules[0];

}
