AddMauiBlazorWebViewDeveloperTools don't exist

Question

In this microsoft documentation is recommended to use builder.Services.AddMauiBlazorWebViewDeveloperTools(); but when i use it my VS gives an error saying that this directive doesn't exist... I'm using builder.Services.AddBlazorWebViewDeveloperTools(); for now.

Does anyone know why I can't use this?

I tried to use this as indicated in the documentation, I looked for some solutions on the internet, but nothing very concrete

You can create a .NET MAUI Blazor app directly. It's the equivalent of adding BlazorWebView to an existing app, automating those steps. For example it contains the following code:

public static class MauiProgram
{
    public static MauiApp CreateMauiApp()
    {
        var builder = MauiApp.CreateBuilder();
        builder
            .UseMauiApp<App>()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
            });

        builder.Services.AddMauiBlazorWebView();
#if DEBUG
        builder.Services.AddMauiBlazorWebViewDeveloperTools();
#endif
        // Register any app services on the IServiceCollection object
        // e.g. builder.Services.AddSingleton<WeatherForecastService>();

        return builder.Build();
    }
}

You can try it. It will not report an error like this: "directive doesn't exist..."
