The Steamworks C# implementations I found that were compatible with Unity have worked for a long time. But I hate them all. For a number of different reasons.
- They're not C#, they're just a collection of functions.
- They're not up to date.
- They require a 3rd party native dll.
- They can't be compiled into a standalone dll (in Unity).
- They're not free
- They have a restrictive license.
C# is meant to make things easier. So lets try to wrap it up in a way that makes it all easier.

}To initialize a client you can do this.
using Steamworks;
// ...
try
{
SteamClient.Init( 4000 );
}
catch ( System.Exception e )
{
// Couldn't init for some reason (steam is closed etc)
}Replace 4000 with the appid of your game. You shouldn't call any Steam functions before you initialize.
When you're done, when you're closing your game, just shutdown.
SteamClient.Shutdown();To create a server do this.
var serverInit = new SteamServerInit( "gmod", "Garry Mode" )
{
GamePort = 28015,
Secure = true,
QueryPort = 28016
};
try
{
Steamworks.SteamServer.Init( 4000, serverInit );
}
catch ( System.Exception )
{
// Couldn't init for some reason (dll errors, blocked ports)
