We should also bump the version here
Once merged and package is published, we should update host to consume this version. Example PR - Azure/azure-functions-host#9740

Seems promising, is it in the next version or just to update the current host package? Thanks a lot!

This will be in the next host version.

sorry for the question. I installed the Azure function tools for local debugging. This seems to have still the old workers and hosts. Any timeline when it is updated or can i download the zip and replace some stuff? Thanks a lot for your work!

Once the host/core tools version with this fix is released, Visual studio will automatically pull in that version for you. Hopefully this will be out in the second half of January.

Thanks. That means Isolated Functions are officially not working on .NET / Azure as long it is not released?
(No clue if it works on azure but makes no sense to deploy untested code? :) )

Isolated functions will work with the existing features. Any new features we ship will be working only after it is officially released.

If you are experiencing issues when using dotnet isolated functions. please open a new GH issue with relevant details. We are happy to help.

Now you make me curious... What i did: Startes Visual Studio, created a isolated function project with a simple httptrigger or scheduled trigger and both did not work at all. In debugging there was the issue that the function host returned a corrupt url. like http://:1234 which seemed to match somehow your fix...?
