FreecraftCore is an open-source C#-based 3.3.5 and 1.12.1 World of Warcraft emulation project. It is derived from the work of Mangos and Trinitycore.

This is a repository of shared .NET/C# libraries between client/server emulation for old World of Warcraft versions. All the old FreecraftCore repositories. All previous repositories, other than the FreecraftCore.Serializer repository, is considered deprecated.

FreecraftCore is built on top of freely available reverse engineering information from the Trinitycore project and the Mangos project. It is a groundup reimplementation of the specifications and protocols outlined in those projects. The focus of FreecraftCore when compared to those projects is the emphasis on shared libraries between client/server for the ultimate creation of an emulated and fully Trinitycore/Mangos compatible client.

Serialization in FreecraftCore takes on a next-generation approach partially outlined by Blizzard themselves, and implemented by mainstream serialization libraries in .NET such as Protobuf-Net and JSON.NET. The FreecraftCore.Serializer leverages metadata/attributes/annotations for controlling serialization behavior. To learn or read more about this implementation see the FreecraftCore.Serializer repository.

Networking for emulation has often been a N:N problem where you need to create N networking clients/libraries for N many projects. This is a significant problem for productivity in emulation. To solve these significant problems, and to take advantage of these problems for the benefit of FreecraftCore, a library called GladNet3 is utilized. This library offers a pipeline API for controling the send and recieve of network messages and abstracting the transportation mechanism as well as providing a simple message handler API. This helps consolidate several projects under one universal networking client/library and API.
