How do I see all services that a .NET IServiceProvider can provide?

Question

This is a general question regarding .NET

I am given an instance of the IServiceProvider interface, but I have little documentation as to what might be possible to get from it. How would I find out a list of all the services it might provide?

Answer 1

Because this is still one of the top suggestions from google:

There is now a nuget extension set that you can pull down from M$ that extends the service provider and exposes several useful endpoints, one of those is "GetServices" which returns an IEnumerable based on the type you provide

https://www.nuget.org/packages/Microsoft.Extensions.DependencyInjection.Abstractions/

Answer 2

There might be a simple solution if you are using Core Web Application. Here's what I ended up doing.

In Startup:

    public void ConfigureServices(IServiceCollection services)
    {
        ...
        services.AddSingleton(services);
    }

This way you can inject the IServiceCollection to any class that needs it.
