There is no registered service of type error in blazor.net when adding a new service

Question

I have set up a sample blazor.net application as per the Docs. After that I created a new service and hard-coded few data and trying to run the application.

But I'm receiving the following error in the console:

There is no registered service of type <applicationName>.App.Services.<serviceName>

It seems the new service name need to register some where, how can I register the new service?

Worth noting that for Blazor WebAssembly, there is no Startup class like the one in Blazor Server. In Blazor WebAssembly we can register Services in Program.cs as below:

public static async Task Main(string[] args)
{
    var builder = WebAssemblyHostBuilder.CreateDefault(args);

    //...other services
    builder.Services.AddSingleton<MyNewService>();

    builder.RootComponents.Add<App>("app");
    await builder.Build().RunAsync();
 }
