.NET 9 Preview 1 extension installed on Windows Function App, how to enable?

Question

I've installed the .NET 9 runtime extension, how do I enable it?
I don't see it present in the version selection dropdown, I've restarted after installing the extension.

Does anyone know? Thanks in advance

I've also tried something like :

az functionapp config set -g GROUPNAME -n APPNAME --net-framework-version v9.0

without success.

Does this extension work?

David Callan Thanks for posting your question in Microsoft Q&A. Currently, Azure Functions supports the below list of versions for Isolated model (refer Languages; Supported versions doc) and .NET 9 is not supported yet. To answer your question, the specific versions of .NET such as .NET 9 cannot be installed via extension. Instead, I suggest you using the supported versions.

I hope this helps and let me know if any questions.
