Creating Neat .NET Core Command Line Apps

You can now read this on my (pretty) website! Check it out here.

Every reason to get more HackerPoints™ is a good one, so today we're going to write a neat command line app in .NET Core! The Common library has a really cool package Microsoft.Extensions.CommandlineUtils to help us parse command line arguments and structure our app, but sadly it's undocumented.

	# Here are a simple and quick steps that does exactly this.
