Photon .NET Client API
Photon is a development framework for multiplayer games.
There are two main APIs to use: "LoadBalancing" and "Chat".
The Loadbalancing API is for room-based games and scalable by using multiple "Game Servers" on demand.
The Chat API allows room-independent communication with friends and in channels.
The Chat API is separated from Loadbalancing and has a special task: It allows communication of users in any number of channels, independent from the matchmaking used for rooms.
Chat is described in the Chat Manual.
