method XXX is inaccessible due to its protection level

I have a strange issue. I use Unity as IOC/DI. I want to create instance of class LoggerService, but the error appers 'LoggerService.LogException(System.Exception, string, string)' is inaccessible due to its protection level'. I have a few classes used by Unity which internal access modifier (no access modifier for class), and thay are accessible in code. Why it not working here?

My code is following:

//console app executable module:
 static void CommonOnUnhandledException(Exception exception, string messagePrefix) 
        {
            var logger = Ioc.Resolve<LoggerService>(Config);
            logger.LogException(exception, String.Empty, String.Empty);
            Console.WriteLine(String.Format("{0} unhandled exception: {1}; {2}", messagePrefix, exception.Message, exception.StackTrace));
        }

//library Services.dll
class LoggerService : ILoggerService 
    {


        public LoggerService(AppConfiguration configuration)
        {
            ...
         }
        public void LogException(Exception ex, string url = "", string messageContent = "")
        {
...

        }
}

//library services dll, started in console app
 public static class ServicesModule
    {
        public static void Init(UnityContainer container)
        {
            // register all other ordinary types:
            container.RegisterType<IIntelShopService, IntelShopService>(new ContainerControlledLifetimeManager());
            container.RegisterType<IBackendService, BackendService>(new ContainerControlledLifetimeManager());
            container.RegisterType<IIntelODataService, IntelODataService>(new ContainerControlledLifetimeManager());
            container.RegisterType<ILoggerService, Log4NetLoggerService>(new ContainerControlledLifetimeManager());
            container.RegisterType<IPerformanceTrackerService, PerformanceTrackerService>(new ContainerControlledLifetimeManager());

        }
    }

You could try to resolve ILoggerService instead of a specific implementation.

If you resolve concrete types instead of interfaces, you're using only half of the power of unity or dependency injection/inversion of control in general.

BTW: the implementations should most of the time be internal, while interfaces on the other hand tend to be public.

You have to make your class public. It's useful to always use a modificator for methods, properties and classes.

You have to make your class public. Without a modifier the default is internal, which is not "visible" enough for your purposes. See also here.
