</ContentPage>

MainPage.cs

namespace Casdoor.MauiOidcClient.Example
{
    public partial class MainPage : ContentPage
    {
        int count = 0;
        private readonly CasdoorClient client;
        private string accessToken;
        public MainPage(CasdoorClient client)
        {
            InitializeComponent();
            this.client = client;

#if WINDOWS
    client.Browser = new WebViewBrowserAuthenticator(WebViewInstance);
#endif
        }

        private void OnCounterClicked(object sender, EventArgs e)
        {
            count++;

            if (count == 1)
                CounterBtn.Text = $"Clicked {count} time";
            else
                CounterBtn.Text = $"Clicked {count} times";

            SemanticScreenReader.Announce(CounterBtn.Text);
        }

        private async void OnLoginClicked(object sender, EventArgs e)
        {
            var loginResult = await client.LoginAsync();
            accessToken = loginResult.AccessToken;
            if (!loginResult.IsError)
            {
                NameLabel.Text = loginResult.User.Identity.Name;
                EmailLabel.Text = loginResult.User.Claims.FirstOrDefault(c => c.Type == "email")?.Value;            

                LoginView.IsVisible = false;
                HomeView.IsVisible = true;
            }
            else
            {
                await DisplayAlert("Error", loginResult.ErrorDescription, "OK");
            }
        }

        private async void OnLogoutClicked(object sender, EventArgs e)
        {
            var logoutResult = await client.LogoutAsync(accessToken);


            if (!logoutResult.IsError)
            {
                HomeView.IsVisible = false;
                LoginView.IsVisible = true;
                this.Focus();
            }
            else
            {
                await DisplayAlert("Error", logoutResult.ErrorDescription, "OK");
            }
        }
    }
}

Paso 5: Soporte para la Plataforma Android

Modifica el archivo AndroidManifest.xml.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <application android:allowBackup="true" android:icon="@mipmap/appicon" android:roundIcon="@mipmap/appicon_round" android:supportsRtl="true"></application>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <queries>
        <intent>
            <action android:name="android.support.customtabs.action.CustomTabsService" />
        </intent>
    </queries>
</manifest>

Paso 6: Lanza la Aplicación
