            IServiceProvider services = new ServiceCollection()
                .AddTransient<MainViewModel>()
                .BuildServiceProvider();
            // Configure the global provider before WPF starts loading StartupUri/XAML
            // The {dxmvvm:Ioc ...} config can resolve types during initialization in XAML
            IocServiceProvider.Default.ConfigureServices(services);
            base.OnStartup(e);

            var mainWindow = new MainWindow();
