How do I use Lidgren.Network? I mean, "install" it so I can use it in my project? Because I would love to get started with simple multiplayer games, but I can't find any good tutorials online, but I've heard that Lidgren.Network is good :D
I tried to just drag the Lidgren.Network into the project, but I couldn't use it that way, I guess it was a really bad idea..
And also, if I make a game using Lidgren.Network for networking, will I be able to sell it? And if not, will I be able to upload it at all?
