Hi, when can we expect java 21 support for Azure functions in Windows. I was told it will be ready by end of March 2025 but still no updates.

Please share the roadmap if you have.

Hi ,

Thanks for reaching out to Microsoft Q&A.

As of today, Azure Functions does not yet support Java 21 on Windows-based function apps. While Java 21 is generally available for Linux-based Azure Functions, its support on Windows remains pending. ​

Previously, the Azure Functions team had estimated Java 21 support for Windows-based function apps by early March 2025. However, as of now, there have been no official updates or announcements confirming this support.​

For the most current information, it's advisable to monitor the Azure Functions language support documentation and the Azure Updates page. ​Microsoft Learn+3Azure documentation+3Azure documentation+3
