+When you create an Azure Functions project from a non-.NET template, extension bundles are already enabled in the app's *host.json* file. 
 
 You define an extension bundle reference in the *host.json* project file by adding an `extensionBundle` section, as in this example: 
 
 [!INCLUDE [functions-extension-bundles-json](../../includes/functions-extension-bundles-json.md)]
