How To Create a UDP Server in C#

This has been requested by multiple people so I decided to make a quick UDP Server tutorial. It is not the best server and I may re-do this one in the future - it only handles 1 connection and closes after the client disconnects/stops sending information. I was cut off at the end so I had to sum up Port Forwarding really quickly so please forgive my rushed-ness. Also I think the quality may be a smidge iffey but it should be good enough for now. If you have any requests feel free to comment/send me a message!
