Creating Functions Locally

Using the IDE

An IDE, such as Visual Studio, should already have an Azure Functions project template. We can select this template while creating a new project, as the following screenshot demonstrates:

We can then follow the steps to select the .NET version and the function type (whether it’s in-process or isolated process). Once the project is created, we will also be able to run it locally by using the UI controls of the IDE, as we would for any other application type.

Using the CLI

Creating and running functions via a CLI is more involved. The process will also differ depending on which operating system we use. The first thing we need to do is install the Azure Functions Core Tools.
