Answer by Liyun Zhang - MSFT for Refresh/Reload MAUI Blazor Hybrid page

That seems to work but it seems like that the memory consumption increases a lot for each refresh/reload so bit worrying

This is not matter. If you open the Task Manager and refresh the brower you will find the browser's memory consumption also increases a lot.

But you can also try to reload the current url in the webview to check the memory consumption.In the MainPage.xaml:

<BlazorWebView x:Name="blazorWebView"/>

In the MainPage.cs:

        public void Reload(string url)        {#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        }

And in the razor page:

@inject NavigationManager nav;@code{   public void Refresh()   {        (App.Current.MainPage as MainPage).Reload(nav.Uri);   }}
