-In this tutorial, you'll learn how to create a .NET MAUI app for Windows in Visual Studio 2022 (17.3 or later) that loads some user data from [Microsoft Graph](/graph/). We will [authenticate](/graph/authenticationmethods-get-started) a Microsoft account with [Azure Identity](/graph/azuread-identity-access-management-concept-overview). The identity information, in the form of an MSAL token, will be used to authorize the Graph SDK call and get the display name for the authenticated user.

     This code first checks to make sure the user has entered a location in the `Entry` control. If not, it displays an alert and returns. If the user has entered a location, it calls the `AskAsync` method on the ChatGptNet library to make a call to the OpenAI ChatGPT API. The `AskAsync` method takes two parameters: a `Guid` that identifies the user's session and a string containing the question to ask the API. The `AskAsync` method returns a `ChatGptResponse` object that contains the response from the API. We'll use the `GetMessage` method on the `ChatGptResponse` object to get the response text and display it in the `Label` control at the bottom of the UI.
 
+1. Add the following `using` statements to the top of the **MainPage.xaml.cs** file:

+    ```csharp
+    using ChatGptNet;
+    using ChatGptNet.Models;

 1. Run the app, enter a location, and test the recommendation buttons. You should see a response from the API in the `Label` control at the bottom of the UI:
