I want to implement dependency injection (DI) in ASP.NET Core. So after adding this code to ConfigureServices method, both ways work.

What is the difference between the services.AddTransient and service.AddScoped methods in ASP.NET Core?

public void ConfigureServices(IServiceCollection services)
{
    // Add framework services.

    // Add application services.
    services.AddTransient<IEmailSender, AuthMessageSender>();
    services.AddScoped<IEmailSender, AuthMessageSender>();
}
