How to deploy Azure Function App on Linux from Visual Studio

Question

How can i deploy an Azure Function App V2 to an existing Linux Function App Plan in Azure from Visual Studio 2019?

When i select "Select existing" from the publish-dialog in Visual Studio i only see my windows-based functions in my connected Azure Subscription, but the Linux one i created in the same subscription is missing.

When i download the publishing profile for the function app, import this and try to publish this way, i get an error which is not very helpful imho:

System.AggregateException: One or more errors occurred. ---> System.Exception: Publishing failed.

1.right click your project in Visual Studio. Select 'Open Floder in File Explorer'.

2.Press the win and R keys at the same time, then type "cmd" and click OK.

3.Go to the folder where the project is located.

4.Then use func azure functionapp publish <APP_NAME>.(each <APP_NAME> is unique on Azure. in myside, it's name is linuxFunctionAppBowman, you can use the name that you created before.)

5.Function been deployed.
