/*
* IContainer inherits ILifetimeScope, and function BeginLifetimeScope is to begin a new nested scope.
* Component instances created via the new scope will be disposed along with it.
* So I think this is a better demo.
*
* Here have three situations:
* 1. Single Instance in every lifetime
* The ILoggers that AccountBll and AccountDal depend on in every lifetime are the same,
* but in different lifetime are different
* cb.RegisterType<ConsoleLogger>().As<ILogger>().InstancePerLifetimeScope();
* 2. Single Instance in entire project
* The ILoggers that AccountBll and AccountDal depend on in every lifetime are the same,
* and in different lifetime are the also the same
* cb.RegisterType<ConsoleLogger>().As<ILogger>().SingleInstance();
* 3. Different instance in every step
* The ILoggers that AccountBll and AccountDal depend on in every lifetime are different,
* and in different lifetime are also different.
* cb.RegisterType<ConsoleLogger>().As<ILogger>();
* We can have a try for every situation. The outputs are different:
* Maybe the "输出日志" is the same, but the logger hashcode in every function is different.
