In Unity, the scripting back end is the runtime technology that compiles and executes your C# scripts. It determines how your code is turned into executable instructions and what runtime manages it on target platforms.
Topic | Description |
|---|---|
| Introduction to scripting back ends | Understand the available scripting backends and their effects on your project. |
| Mono scripting back end | Mono is a stable, mature .NET runtime that provides a managed environment for the just-in-time (JIT) compilation of your C# code. |
| IL2CPP scripting back end | IL2CPP is Unity's ahead-of-time (AOT) pipeline that converts C# intermediate language (IL) to C++, then compiles to native code. It's required on several platforms where Mono and JIT are not supported. |
| CoreCLR scripting back end (Experimental) | CoreCLR is the open-source, cross-platform .NET runtime maintained by the .NET Foundation as part of the modern .NET platform (the successor to .NET Core). It provides the execution engine, garbage collector, and just-in-time (JIT) compiler that power .NET applications across Windows, macOS, and Linux. |
