A C# wrapper class #20
Description
I'm using GodotSteam C# bindings and saw there wasn't a C# wrapper for SteamMultiplayerPeer.
Not sure if there is one already but I've made a start but its missing a lot.
Its not establishing a connection to the host though. I thought it was maybe an issue with my project, but when I checkout the demo its also not establishing a connection with the host.
