Creating an Azure function through the portal

Question

From within the Function App, I can't create a function through the portal. It only shows me VS Code or VS. Apparently this is a problem many people have posted in various forums with no solution.

Hi Russell,

First, only certain language/stack/operating system combinations are supported for in-portal editing, as shown in table below. For example, if you are using Java then you wouldn't have the option to create/edit via the portal. Below table is from language support details article:

Language	Runtime stack	Linux	Windows	In-portal editing
C# (isolated worker model)	.NET	✓	✓
C# (in-process model)	.NET	✓	✓
C# script	.NET	✓	✓	✓
JavaScript	Node.js	✓	✓	✓
Python	Python	✓	X	✓
Java	Java	✓	✓
PowerShell	PowerShell Core	✓	✓	✓
TypeScript	Node.js	✓	✓
Go/Rust/other	Custom Handlers	✓	✓

Second, if you deploy a function using Visual Studio Code or Visual Studio or CLI or other non-portal method the ability to edit functions via the portal will be disabled for that function app.

Third, creating/editing functions in the portal is typically only for demo/testing purposes. In most cases you should be using a local development environment like VS Code, VS, Neovim, etc.
