Good day, I wrote my own .dll for Networking Operations that I now would like to use within Unity. But I'm not quite satisfied by adding a new Reference to each new MonoBehaviour Class I write. So, what's the best way to this? Is it even recommended? I used the Search, but I didn't find any post exactly describing my problem here. Edit: Since I'm bad at asking questions, here's the same question, rephrased: Did anyone ever use external Libraries in Unity over Visual Studio? If yes, how did you "install" them?
