IL2CPP (Intermediate Language To C++) is a Unity-developed scripting backend which you can use as an alternative to Mono when building projects for various platforms. When building a project using IL2CPP, Unity converts IL code from scripts and assemblies to C++, before creating a native binary file (.exe, apk, .xap, for example) for your chosen platform. Some of the uses for IL2CPP include increasing the performance, security, and platform compatibility of your Unity projects.
Para obtener más información sobre el uso de IL2CPP, consulte la serie de blogs The Unity IL2CPP y las siguientes páginas del Manual de Unity.
See the Scripting Restrictions page for details about which platforms support IL2CPP.
IL2CPP supports debugging of managed code in the same way as the Mono scripting backend.
