我通常在 XAML 中直接绑定到 ViewModel.然后在 OnNavigatedTo 我触发视图模型以异步获取其数据.

I usualy bind to a ViewModel directly in XAML. Then in OnNavigatedTo I trigger the view model to fetch its data async.

这允许我从一开始就显示基本值(页面标题等).然后，当我开始获取数据时，我还可以直接在 ViewModel 中激活进度条，然后在获取数据后将其删除.

This allows me to show basic values from start (page title etc.). Then when I start fetching the data I can also activate a progressbar directly in the ViewModel and then remove it once the data is fetched.
