Different from the IServiceProvider, the IServiceCollection can't be injected into a class constructor. As many have already said, you should avoid using them directly. But if you really need to do so for the IServiceCollection, you can create a "Provider", such as:

The solution I came up with was to use the injected IServiceCollection to build an IServiceProvider to get the configured service I needed. As I pointed out at the time, this service-locator pattern felt icky and wrong, but I couldn't see any other way of doing it. I have added a class in ConfigureServices(IServiceCollection services) as services.AddInstance(Configuration);I want to get the instance in my HostConfiguration.cs class, I can get it in controller, problem is how can i get it in any other class? In unity we can use ServiceLocator to get instance, Now in MVC 6 how can i get it?

public static T GetService ( this IServiceProvider provider); C#. AddOptions(IServiceCollection) Adds services required for using options. AddOptions(IServiceCollection) Gets an options builder that forwards Configure calls for the same named TOptions to the underlying service collection.

The main benefit of GetRequiredService() over GetService() is that it allows third-party containers to provide additional diagnostic information when a requested service is not available. The problem is that the service provider is a temporary "root" service provider. It creates the services and injects them into Startup . The remainder of the dependency injection container configuration then runs as part of ConfigureServices , and the temporary service provider is thrown away.
