For issues relating to the IL2CPP Unity scripting back-end.

IL2CPP is a Unity-developed scripting back-end which can be used as an alternative to Mono when building projects for some platforms. Therefore Unity converts IL code from scripts and assemblies into C++ code, before creating a native binary file (.exe, apk, .xap, for example) for a chosen platform.
