Seems there have been two changes that are getting in the way of creating functions after having created a function ressource. There is no longer the "Function f(x)" under the left menu called Functions, and seems we can only access it now from the Overview section. Why not. When accessing that from the Overview section, there isn't a possibility for me to create a serverless function directly in Azure Portal. My question is therefore, how can I create a function direclty in Azure Portal, given these changes in UI?

@NT Thanks for reaching out. It is true that the Azure Portal UI has changed recently, and the "Function f(x)" option is no longer available in the left-hand menu. Instead, you can access the Functions from the "Overview" section of the Azure Portal. Portal only supports creating functions using scripting languages such as JavaScript, Python, and PowerShell. If you want to create a compiled function, you will need to use a development environment such as Visual Studio or Visual Studio Code to create and deploy your function. do let me know incase of further queries, I would be happy to assist you. Please 'Accept as answer' and ‘Upvote’ if it helped so that it can help others in the community looking for help on similar topics.

If you had selected .NET as the Stack then you will need to change a setting value in the Environment Variables section of your Function app -> App Settings -> "FUNCTION_WORKER_RUNTIME" from "dotnet-isolated" to "dotnet", and then save this change. When you go back to Overview, you can find the "Create in Azure Portal" option will appear. If you selected any other stack, this option should be visible by default.

Thanks for your answer. I get the first point, but not the second. I created the Function Application resource and precised I wanted it to be in Python. As you said, Portal supports python. So I don't understand why I can't create a Function simply in the portal (I don't want to have to do it locally or in VS code, I'd rather do it directly in the Azure portal - with python). Could you help me with that?

I am not sure if this is what solved the issue, but I basically upgraded to a Pay as you go subscription and this seems to have solved the issue and now I have the option in Overview to create it within the Azure Portal. Weird thing is that I created a new subscription for the pay as you go plan and used the previous Free tier subscription. So not sure that this is actually what solved the issue. Thanks for your help.

NT Thanks for the update. This issue can happen if your using free tier. If you switch subscription from Free to Pay As You Go the option to create functions in the portal will appear. I believe that Functions are one of the services that does not qualify for the free tier. https://learn.microsoft.com/en-us/answers/questions/614084/unable-to-create-function-in-function-app

I created using a free tier, an azure function app that used .Net Runtime 4.834.3.22875,

and I am able to add functions using the Portal.

When I use the latest runtime I am NOT able to add function using the Portal

Yes, I also found through trial-and-error that "Create in Azure Portal" is only available for the .NET 6 in-process worker model. This .NET version will stop receiving security updates after November 2024. As of yet, there is no in-process worker model for any more recent .NET version. I found a roadmap, though, without specific dates: https://techcommunity.microsoft.com/t5/apps-on-azure-blog/net-on-azure-functions-march-2024-roadmap-update/ba-p/4097744

So be aware, if you're creating something new using the in-process model, you'll need to use the outdated .NET 6 for now and migrate your function app to .NET 8 within a few months for it to keep receiving security updates.

Fortunately for me, I don't really care about "Create in Azure Portal", except for following along with certain tutorials.
