The container can't be changed after the first call to GetInstance, GetAllInstances, Verify, and some calls of GetRegistration

问题

I cant figure out why I am getting this error below within the RegisterCollection method. Am I doing the setup incorrectly?

The container can't be changed after the first call to GetInstance, GetAllInstances, Verify, and some calls of GetRegistration. Please see https://simpleinjector.org/locked to understand why the container is locked. The following stack trace describes the location where the container was locked:

Logger registration

 public static void Register(Container container)
 {
     container.RegisterConditional(typeof(ILogger), 
        c => typeof(NLogLogger<>).MakeGenericType(
            c.Consumer?.ImplementationType ?? typeof(object)),
        Lifestyle.Transient, 
        c => true);

...

}

container.RegisterCollection throws the error

container.Register<IEmailTemplatesService>(() => new EmailTemplatesService(emailTemplates,
    container.GetInstance<IEventEmailTemplatesRepository>(),
    container.GetInstance<IEmailTemplatesRepository>(),
    container.GetInstance<IEventSettingsRepository>(),
    container.GetInstance<IEmailsService>(),
    container.GetInstance<IUnitOfWork>(),
    container.GetInstance<IValidationProvider>()));

container.RegisterCollection<IStreamingMethod>(new List<IStreamingMethod>
{
    new CubeProvider(container.GetInstance<ILogger>()),
    new BallerTvProvider(container.GetInstance<ILogger>())
});

You are getting this error because you are calling GetInstance during your container setup. As the exception and the referenced documentation explain, this is not allowed.

The problem is caused by you trying to partially hand-wire your registrations, while you should prefer letting Simple Injector do the heavy lifting and Auto-Wire everything for you. You should therefore change your registration to the following:

container.Register<IEmailTemplatesService, EmailTemplatesService>();

container.RegisterCollection<IStreamingMethod>(new[]
{
    typeof(CubeProvider),
    typeof(BallerTvProvider)
});
