Let's begin by making a new folder in which to store our new extension! We'll create a couple of crucial files in this folder that make up the anatomy of an Azure DevOps extension. These are the files:

The fundamental definition of our extension is the manifest file (vss-extension.json).
The task manifest file(s) (task.json), our task definitions, which scripts to run, and which task input parameters to display.
The task script file(s) (.ps1/.js), which contain the scripts that are run according to the task.json configuration.
You have the option of using javascript (.js) or powershell (.ps1) files. The powershell files will be used in our situation.
Modules for completing tasks (for example, the VstsTaskSdk module)
