Perhaps one of the single greatest advantages of using connectionless communication, such as UDP, is the ability to send out packets to a large number of recipients in a single transaction. This is commonly called multicasting, or broadcasting, and it enables everything from network device discovery and host registration to most live television or video streams broadcast over the internet. It's a somewhat niche feature that, if I had to guess, most of the people reading this will never have a good reason to leverage, but it is certainly worth understanding. With that said, let's look at how to enable this feature in our .NET Core apps.
