WebView2 on Xbox: Navigating to local html file results in edge blocking loading

[kizerkizer]

Hello,

I am developing a UWP application for Xbox that utilizes WebView2. In my project in visual studio, I have a HTML file whose
"Copy to Output Directory" property I've set to "Copy always". I navigate the webview to this file at runtime:

string page = "file:///" + Directory.GetCurrentDirectory().Replace('\\', '/') + "/www/index.html";
this.WebView.Source = new Uri(page);

This works fine on my local machine, but when I debug on Xbox I get an error page that says: "This page has been blocked by Microsoft Edge". Error code is ERR_BLOCKED_BY_CLIENT.

I assume there is an issue regarding permission to load the local file on Xbox? Is there another way to load a local html file?

I was able to make it work by using the same method used in the Media App Samples for Xbox repository. Like so:

        private async void SetupWebview ()
        {
            await WebView.EnsureCoreWebView2Async();
            string page = "https://localHTML/index.html";
            WebView.CoreWebView2.SetVirtualHostNameToFolderMapping("localHTML", "www", Microsoft.Web.WebView2.Core.CoreWebView2HostResourceAccessKind.Allow);
            WebView.Source = new Uri(page);

        }
