Iservicescopefactory vs iserviceprovider

IServiceScopeFactory is always a Singleton but the IServiceProvider can vary based on the lifetime of the containing class. So if you create a scope and resolve services from this scope, and any of those services take an IServiceProvider, it'll be the scoped one. cc @IEvangelist some docs to add很明显,每次调用IServiceScopeFactory.CreateScope()都会创建一个新的IServiceScope;但是,调用IServiceProvider.CreateScope()扩展方法是否每次都会创建一个新的IServiceScope? 基本上,在ASP.NET Core和.NET Core控制台应用程序中创建范围的以下方法之间是否存在有意义的差异:

GetService vs GetRequiredService . GetService和GetRequiredService是IServiceProvider下的两个扩展方法,用它们可以获取服务的实例,上面提到过,在进行操作的时候,如果该IServiceProvider在根容器中,你要格外的小心。 那么GetService和GetRequiredService有什么区别呢?
