 # Add Login to Your UWP application
 
-
 <p>This tutorial demonstrates how to add user login to a UWP C# application using Auth0. We recommend that you log in to follow this quickstart with examples configured for your account.</p><h2>System Requirements</h2><p>This tutorial and sample project have been tested with the following:</p><ul><li><p>Microsoft Visual Studio 2022</p></li><li><p>Windows 10 SDK (10.0.26100.0)</p></li><li><p>Auth0.OidcClient.UWP 4.0.0</p></li></ul><div></div><p></p>
 
+# Configure Auth0
+
+<%= include('../_includes/_getting_started', { library: 'Windows Universal' }) %>
+
+<%= include('../../../_includes/_callback_url') %>
+
+::: note
+If you are following along with the sample project you downloaded from the top of this page, you should set the **Allowed Callback URLs** to `https://${account.namespace}/mobile`.
+:::
+
+<%= include('../../../_includes/_logout_url', { returnTo: 'https://' + account.namespace + '/mobile' }) %>
+
+# Integrate Auth0 in your Application
+
+## Install Dependencies
+
+Use the NuGet Package Manager Console (Tools -> NuGet Package Manager -> Package Manager Console) to install the `Auth0.OidcClient.UWP` package, running the command:
+
+${snippet(meta.snippets.dependencies)}
+
+## Trigger Authentication {{{ data-action="code" data-code="MainPage.xaml.cs" }}}
+
+To integrate Auth0 login into your application, simply instantiate an instance of the `Auth0Client` class, configuring the Auth0 Domain and Client ID:
+
+${snippet(meta.snippets.setup)}
+
+You can then call the `LoginAsync` method to log the user in:
+
+${snippet(meta.snippets.use)}
+
+![](/media/articles/native-platforms/windows-uwp-csharp/universal-login.png)
+
+This loads the Auth0 login page into a web view. You can learn how to customize the login page at <a href="/universal-login#simple-customization" target="_blank" rel="noreferrer">this document</a>.
+
+## Handle Authentication Tokens
+
+The returned login result indicates whether authentication was successful, and if so contains the tokens and claims of the user.
+
+### Authentication Error
+
+You can check the `IsError` property of the result to see whether the login has failed. The `ErrorMessage` contains more information regarding the error which occurred.
+
+```csharp
+if (loginResult.IsError)
+{
+    Debug.WriteLine($"An error occurred during login: {loginResult.Error}")
+}
+```
+
+### Accessing the tokens
+
+On successful login, the login result contains the ID Token and Access Token in the `IdentityToken` and `AccessToken` properties respectively.
+
+```csharp
+if (!loginResult.IsError)
+{
+    Debug.WriteLine($"id_token: {loginResult.IdentityToken}");
+    Debug.WriteLine($"access_token: {loginResult.AccessToken}");
+}
+```
+
+### Obtaining the User Information
+
+On successful login, the login result contains the user information in the `User` property, which is a <a href="https://msdn.microsoft.com/en-us/library/system.security.claims.claimsprincipal(v=vs.110).aspx" target="_blank" rel="noreferrer">ClaimsPrincipal</a>.
+
+To obtain information about the user, you can query the claims. You can for example obtain the user's name and email address from the `name` and `email` claims:
+
+```csharp
+if (!loginResult.IsError)
+{
+    Debug.WriteLine($"name: {loginResult.User.FindFirst(c => c.Type == "name")?.Value}");
+    Debug.WriteLine($"email: {loginResult.User.FindFirst(c => c.Type == "email")?.Value}");
+}
+```
+
+::: note
+The exact claims returned depends on the scopes that were requested. For more information see @scopes.
+:::
+
+You can obtain a list of all the claims contained in the ID Token by iterating through the `Claims` collection:
+
+```csharp
+if (!loginResult.IsError)
+{
+    foreach (var claim in loginResult.User.Claims)
+    {
+        Debug.WriteLine($"{claim.Type} = {claim.Value}");
+    }
+}
+```
+
+## Logout
+
+To log the user out call the `LogoutAsync` method.
+
+```csharp
+await client.LogoutAsync();
+```
