It was a Sunday afternoon and I wanted to play with some of the new features of .NET 5 and learn something. I had a small irritation with bit.ly. When I customized a short-URL, I could never go back and update the link. That was enough for me to want to make something.
I hope you're watching the .NET Conf happening this week. If you have, you know that .NET 5 was finally released. This version isn't a long-term support (LTS) version, but that doesn't mean that many people will be using it in production...at least I will be.
