For Blazor WASM you setup the DI in Program using WebAssemblyHostBuilder.Services:

public class Program
{
    public static async Task Main(string[] args)
    {
       var builder = WebAssemblyHostBuilder.CreateDefault(args);
       builder.Services.AddSingleton<SengaltonServices>();
       await builder.Build().RunAsync();
    }
}
