Supported languages in Azure Functions
This article explains the levels of support offered for languages that you can use with Azure Functions.
Levels of support
There are three levels of support:
- Generally available (GA) - Fully supported and approved for production use.
- Preview - Not yet supported but is expected to reach GA status in the future.
- Experimental - Not supported and might be abandoned in the future; no guarantee of eventual preview or GA status.
Languages in runtime 1.x and 2.x
Two versions of the Azure Functions runtime are available. The following table shows which languages are supported in each runtime version.
|C#||GA (.NET Framework 4.7)||GA (.NET Core 2)|
|F#||GA (.NET Framework 4.7)||GA (.NET Core 2)|
|Java||N/A||GA (Java 8)|
|Python||Experimental||Preview (Python 3.6)|
|Batch (.cmd, .bat)||Experimental||N/A|
For information about planned changes to language support, see Azure roadmap.
The experimental languages in version 1.x don't scale well and don't support all bindings. For example, experimental support for PowerShell in 1.x is limited to version 5.1, because that is what's installed by default on the VMs on which function apps run. If you want to run PowerShell scripts, consider Azure Automation.
Don't use experimental features for anything that you rely on, as there is no official support for them. Support cases should not be opened for problems with experimental languages.
The version 2.x runtime doesn't support experimental languages. Support for new languages is added only when the language can be supported in production.
