 For an app to authenticate to Azure during local development using the developer's Azure credentials, the developer must be signed-in to Azure from one of the following developer tools:
 
+- Visual Studio
+- Visual Studio Code
 - Azure CLI
-- Azure Developer CLI
 - Azure PowerShell
-- Visual Studio
+- Azure Developer CLI
 
 The Azure Identity library can detect that the developer is signed-in from one of these tools. The library can then obtain the Microsoft Entra access token via the tool to authenticate the app to Azure as the signed-in user.
