C# WebBrowser -> WebView2 solution

Hi The_Doc eJulia 

I already posted the solution for .NET based on The_Doc findings about 9 days ago:

1. Change webB.DocumentText to webB.Url.AbsoluteUri
2. Replace ExtractSubstring with:

        private static string ExtractAuthorizationCode(string uri)
        {
            var uriObj = new Uri(uri);
            var queryParams = HttpUtility.ParseQueryString(uriObj.Query);
            return queryParams["code"];
        }

I understand finding solutions in these threads is tricky 🙂
