Logging in .NET Core without DI?

Question

It seems that Microsoft are really trying to shove DI down your throat with .NET Core, and I'm not sure why, but frankly my console app is small and simple and I just don't want to build a whole DI container just to do some simple logging. How can I do logging in .NET Core without using DI? Everything I've read assumed you're going to use .NET Core's built-in logging architecture which obviously requires DI, but there must be a way to just do it without DI using a static variable on the class?

If you want to do it yourself you will need to instantiate a LoggerFactory instance somewhere and configure what providers you want. Then you just need to call CreateLogger to create a instance or use new Logger<T>(ILoggerFactory) to create a logger.

using Microsoft.Extensions.Logging;  static class MyLogger {      public static ILoggerFactory LoggerFactory {get;}      static MyLogger() {         LoggerFactory = new LoggerFactory();         LoggerFactory.AddConsole();     } }  public MyClass {     private readonly ILogger _logger = new Logger<MyClass>(MyLogger.LoggerFactory); }
