1、InstancePerDependency
对每一个依赖或每一次调用创建一个新的唯一的实例。这也是默认的创建实例的方式。
官方文档解释：Configure the component so that every dependent component or call to Resolve() gets a new, unique instance (default.)
2、InstancePerLifetimeScope
在一个生命周期域中，每一个依赖或调用创建一个单一的共享的实例，且每一个不同的生命周期域，实例是唯一的，不共享的。
官方文档解释：Configure
the component so that every dependent component or call to Resolve()
within a single ILifetimeScope gets the same, shared instance. Dependent
components in different lifetime
scopes will get different instances.
3、InstancePerMatchingLifetimeScope
在一个做标识的生命周期域中，每一个依赖或调用创建一个单一的共享的实例。打了标识了的生命周期域中的子标识域中可以共享父级域中的实例。若在整个继承层次中没有找到打标识的生命周期域，则会抛出异常：DependencyResolutionException。
官方文档解释：Configure
the component so that every dependent component or call to Resolve()
within a ILifetimeScope tagged with any of the provided tags value gets
the same, shared instance. Dependent
components in lifetime scopes that are children of the tagged scope
will share the parent‘s instance. If no appropriately tagged scope can
be found in the hierarchy an DependencyResolutionException is
thrown.
4、InstancePerOwned
在一个生命周期域中所拥有的实例创建的生命周期中，每一个依赖组件或调用Resolve()方法创建一个单一的共享的实例，并且子生命周期域共享父生命周期域中的实例。若在继承层级中没有发现合适的拥有子实例的生命周期域，则抛出异常：DependencyResolutionException。
官方文档解释：Configure
the component so that every dependent component or call to Resolve()
within a ILifetimeScope created by an owned instance gets the same,
shared instance. Dependent components
in lifetime scopes that are children of the owned instance scope will
share the parent‘s instance. If no appropriate owned instance scope can
be found in the hierarchy an DependencyResolutionException is
thrown.
5、SingleInstance
每一次依赖组件或调用Resolve()方法都会得到一个相同的共享的实例。其实就是单例模式。
官方文档解释：Configure the component so that every dependent component or call to Resolve() gets the same, shared instance.
6、InstancePerHttpRequest
在一次Http请求上下文中,共享一个组件实例。仅适用于asp.net mvc开发。
官方文档解释：Share one instance of the component within the context of a single HTTP request.
