Logging in .NET Core without DI?

As per Ilyas and bokibegs comments in Scotts answer here is the currently working code for .NET 5.0:

using Microsoft.Extensions.Logging;

var factory = LoggerFactory.Create(builder => {
    builder.AddConsole();
});

var logger = factory.CreateLogger<T>();

This requires the Microsoft.Extensions.Logging and Microsoft.Extensions.Logging.Console nuget packages.
