Hello @MughundhanRaveendran-MSFT ,

Thank you for answer.
I understand that func azure functionapp publish <FunctionAppName> deploys your code it also deletes existing ones!

From ACE Portal, you can add multiple functions within your <FunctionAppName> but if you were to deploy one with func azure functionapp publish <FunctionAppName> , it would delete all of them first and deploy the last one you pushed. Which is what I am trying to figure out..

The goal is having more than one functions within a function app!

Thanks again,
~cem

@Bakar, Cem , yes you are correct. Exisiting function will be deleted and overwritten by the newly published functions. This is by design. I would suggest you to keep all your functions within one function app project and deploy in one go. You can either create and develop the function in Azure portal (.net and powershell) or deploy pre-compiled code but you cannot keep both. In my case, I created http,blob,queue triggers in one function app and deployed in one go. This way I deploy more than one function within a function app, this way you can achieve your goal.

I hope this clears. Please let me know if you have any further questions

@MughundhanRaveendran-MSFT If you consolidate all functions under one project, it makes it impossible to run/debug them individually in VS2022, which renders your recommendation untenable.

There must be a better way to manage multiple projects in VS2022 that are individual functions and then be able to publish them all under a single Function app.

Hi @Bakar, Cem ,

Thanks for reaching out to Q&A forum.

As you mentioned, when you deploy the code to an existing function, the contents will be overwritten. If you would like to deploy multiple functions, I would suggest you to add multiple functions to one function app (same language stack) and then deploy using the function core tools. Please see below example,

My function app is MyFunctionProj, I have http and blob triggered function

I will add a queue storage trigger by using the command "func new" inside the MyFunctionProj folder which has the main function app

Ref : https://learn.microsoft.com/en-us/azure/azure-functions/functions-run-local?tabs=v4%2Cwindows%2Ccsharp%2Cportal%2Cbash#create-func

Once you create all the functions, you can publish to Azure functions runtime using the below command

func azure functionapp publish <FunctionAppName>

I hope this helps! Feel free to reach out to me if you have any queries or concerns.
