Example code in ITypedHttpClientFactory<TClient> Interface page is broken

[milleniumbug]

https://github.com/dotnet/dotnet-api-docs/blob/main/xml/Microsoft.Extensions.Http/ITypedHttpClientFactory%601.xml

// in Controllers/HomeController.cs
public class HomeController : ControllerBase(IApplicationBuilder app, ExampleClient exampleClient)
{
    private readonly ExampleClient _exampleClient;

    public HomeController(ExampleClient exampleClient)
    {
        _exampleClient = exampleClient;
    }

    public async Task<IActionResult> Index()
    {
        var response = await _exampleClient.GetAsync("/helloworld");
        var text = await response.Content.ReadAsStringAsync();
        return Content("Remote server said: " + text, "text/plain");
    };
}

1.) I don't think the ControllerBase(IApplicationBuilder app, ExampleClient exampleClient) syntax exists
2.) ExampleClient does not have a GetAsync method
3.) semicolon after Index()'s method body
