Answer by Liyun Zhang - MSFT for Reload BlazorWebView in a MAUI xaml page

In my test, the blazorwebview's default url is https://0.0.0.0/, so you can call the platform code to reload the url. But to make the url always correct, I get it programmatically.

In the MainPage:

public partial class MainPage : ContentPage    {        public string url;        public BlazorWebView view;        public MainPage()        {            InitializeComponent();            view = blazorWebView;        }        public void Reload()        {#if Android            var androidweb = blazorWebView.Handler.PlatformView as Android.Webkit.WebView;            androidweb.LoadUrl(url);#elif WINDOWS            var windowweb = blazorWebView.Handler.PlatformView as Microsoft.UI.Xaml.Controls.WebView2;            windowweb.Source = new Uri(url);#elif IOS            var iosweb = blazorWebView.Handler.PlatformView as WebKit.WKWebView;            iosweb.LoadRequest(new Foundation.NSUrlRequest(new Uri(url)));#endif        }    }

In the Home.Razor:

@code{   protected override void OnInitialized()   {       base.OnInitialized();#if Android        var androidweb = (App.Current.MainPage as MainPage).view.Handler.PlatformView as Android.Webkit.WebView;        (App.Current.MainPage as MainPage).url = androidweb.Url;#elif WINDOWS        var windowweb = (App.Current.MainPage as MainPage).view.Handler.PlatformView as Microsoft.UI.Xaml.Controls.WebView2;        (App.Current.MainPage as MainPage).url = windowweb.Source.ToString();#elif IOS        var iosweb = (App.Current.MainPage as MainPage).view.Handler.PlatformView as WebKit.WKWebView;        (App.Current.MainPage as MainPage).url = iosweb.Url.ToString();#endif   }}

And then you can call the Reload method to reload the blazor webview. Why I get the default Url in the Home.Razor is I can't get it in the MainPage's life cycle method on the windows platform.
