How do I access Configuration in any class in ASP.NET Core?

Question

I have gone through configuration documentation on ASP.NET core. Documentation says you can access configuration from anywhere in the application.

Below is Startup.c

Answer 1

There is also an option to make configuration static in startup.cs so that what you can access it anywhere with ease, static variables are convenient huh!

public Startup(IConfiguration configuration)
{
    Configuration = configuration;
}

internal static IConfiguration Configuration { get; private set; }

This makes configuration accessible anywhere using Startup.Configuration.GetSection... What can go wrong?
