Scripting backends
Unity has two scripting backendsA framework that powers scripting in Unity. Unity supports three different scripting backends depending on target platform: Mono, .NET and IL2CPP. Universal Windows Platform, however, supports only two: .NET and IL2CPP. More info
See in Glossary: Mono and IL2CPPA Unity-developed scripting back-end which you can use as an alternative to Mono when building projects for some platforms. More info
See in Glossary (Intermediate Language To C++), each of which uses a different compilation technique:
- Mono uses just-in-time (JIT) compilation and compiles code on demand at runtime.
- IL2CPP uses ahead-of-time (AOT) compilation and compiles your entire application before it is run.
This section contains further information about these backends:
| Page | Description |
|---|---|
| Mono overview | Information about the Mono scripting back end. |
| IL2CPP overview | Information about the IL2CPP scripting back end. |
| Scripting restrictions | This section contains information on what scripting restrictions apply to each platform you want to build your application for, to support cross-platform code. |
| Managed code stripping | Information about managed code stripping, which removes unused code from a build. This helps decrease the final build size of your application. |
