```csharp
//Declare a client
var aic = new OpenAIClient(apiKey);

//Get a response
var response = await aic.GetResponseAsync(
   OpenAIClient.GPT51("It's this easy to message AI??")
   .WithInstructions("You're a helpful assistant, respond kindly and to the point"));

//Use the built in MessageContent Property to retrieve the latest message
if (response.IsSuccessful)
    Console.WriteLine(response.Data.MessageContent);
```

{% endcode %}
