Ludosity's Steamworks Wrapper

Ludosity’s Steamworks Wrapper is a fully managed .NET wrapper for the Steamworks API developed by Ludosity AB. The purpose is to make it easier to implement Steamworks features in games using Unity as well as XNA / Monogame.
The library aims to be a complete a 1-to-1 mapping of the Steamworks C++ API. This means that the usage pattern is more or less the same as if C++ where used. This also means that the official help resources can be used as most things will work the same. The main differences are how callbacks are handled.
